E-ATX motherboard support

The HYXN H2 2026 is a large ATX mid-tower with a 4.3 rating and a notably ambitious cooling layout. Its defining feature is support for 420mm radiators, including dual-layer fan arrangements, plus configurations using two 420mm or three 360mm radiators simultaneously. That makes it one of the most flexible chassis in this guide for elaborate custom-loop builds.

Pros

  • Exceptionally broad radiator support
  • Eight fans included from the start
  • Large E-ATX component capacity
  • Generous 455mm GPU clearance
  • Separate rear cable compartment

Cons

  • No ARGB in included fans

Eight fans come preinstalled: six 140mm reverse-blade models and two 120mm forward-blade models. The larger fans provide strong airflow potential, while the separated power-supply and drive chamber keeps the main compartment visually organized. The case also supports E-ATX through ITX motherboards, GPUs up to 455mm, and power supplies up to 220mm, giving it useful headroom for large components.

The trade-off is that the included fans do not have ARGB lighting, despite the case's tempered-glass presentation. Its dimensions are also substantial, so owners should confirm desk clearance before ordering. Even so, those limitations are modest compared with the flexibility offered for users intending to install multiple radiators or a long, high-end graphics card.

Choose the H2 when radiator capacity is the defining requirement and the visual emphasis is on airflow rather than coordinated lighting. It is especially suitable for advanced builders who understand pump placement, reservoir positioning, tubing routes, and the practical consequences of installing very large coolers. For those priorities, it offers exceptional configuration freedom.

Built for Complex Custom Loops

The support for two 420mm or three 360mm radiators creates room for serious heat-transfer capacity. Buyers should still plan pump and reservoir locations carefully because radiator dimensions alone do not guarantee effortless tubing paths.

Large Components Need Large Clearance

Motherboard support reaches E-ATX, graphics card clearance reaches 455mm, and PSU support reaches 220mm. These figures provide useful margins for modern enthusiast hardware and unusually long power cables.

A single F420 RGB Core single-frame fan unit arrives in the front-right position, accompanied by an F120Q case-version fan at the rear. The enclosure can ultimately hold up to nine 140mm fans across the top, front-right, and bottom, plus the rear 120mm fan. Perforated steel panels and angled front-right fans reinforce the emphasis on directional airflow.

The included F120Q is a three-pin DC case version rather than a PWM model, so enthusiasts with fully controllable setups may replace it. Although the H9 accommodates substantial hardware, it does not offer the near-limitless radiator arrangement of the HAVN HS 420. Its wraparound tempered glass, wide cable channels, built-in straps, and tie-down points nevertheless make the chassis unusually builder-friendly.

This is the most broadly appealing option in the guide for a high-quality dual-chamber water-cooled build. It suits buyers who want serious cooling capacity, integrated lighting, and organized wiring without choosing the most specialized or expansive platform. It is also ready for rear-connect motherboards, including ASUS BTF and MSI Project Zero designs.

Radiators in the Right Places

Top and front-right mounting positions match the two areas where custom-loop builders commonly want radiator capacity. The result is a balanced layout for pairing a CPU loop with a dedicated GPU loop.

Cleaner Builds by Design

Extra-wide routing channels, built-in Velcro straps, and dedicated tie-down points reduce the effort required to conceal cables. Rear-connect motherboard support can eliminate many of the visible wires around the main chamber.

Four 120mm ARGB Lite fans with hydraulic bearings are preinstalled, providing lighting and airflow without requiring a separate fan purchase. The pillarless front and side tempered-glass panels present the interior from multiple angles, while compatibility with hidden-connector motherboards supports a particularly clean final appearance. Maximum radiator support is 360mm, and graphics cards up to 415mm fit.

Its limitation is that the 360mm maximum is less flexible than the H9 Flow and HS 420, which can accept 420mm radiators. It is better understood as a well-equipped single-radiator platform than a foundation for a three-radiator showcase loop. Prospective buyers should also verify the exact pump and reservoir placement available for their preferred loop design.

For a straightforward custom loop, the View 380 TG ARGB provides an appealing mix of visual presentation, useful clearance, and preinstalled ARGB fans. It is a strong recommendation for value-conscious builders who want a polished dual-chamber enclosure without assembling every cooling component from scratch.

A Complete Initial Cooling Package

Four preinstalled ARGB Lite fans reduce both cost and setup work at the start of a build. They can serve as part of the radiator airflow while additional case fans are added later if the chosen loop requires more intake or exhaust.

Glass Without Losing Function

The pillarless front and side panels emphasize the water-cooling hardware and internal components. Hidden-connector motherboard compatibility further improves the visual result by reducing cable clutter behind the motherboard tray.

We may earn a commission when you buy through this link, at no additional cost to you.

The case supports dual 360mm radiators, providing a practical route to substantial heat-transfer capacity without requiring three separate mounting zones. It accommodates graphics cards up to 410mm and supports vertical GPU mounting, which can improve the visual presentation of a large card. Four PWM ARGB fans are included, giving the build a useful blend of lighting and airflow from the beginning.

One important note is that the RGB hub is not included. Users who want all lighting to operate from a single control solution may need to add a hub or account for separate motherboard and controller connections. As a full tower, it also demands more desk or floor space than the mid-tower alternatives in this list.

The DY470 is most appropriate for a creator workstation, high-end gaming system, or showcase build that needs generous volume and room for two radiators. Buyers prioritizing a compact footprint should look elsewhere, but those willing to use the larger enclosure gain flexible mounting, long-card clearance, and an attractive angled-glass design.

Room for Two 360mm Radiators

Dual-radiator support is ideal for separating a CPU loop and GPU loop or increasing total radiator area. Pump, reservoir, and tubing routes should be sketched against the available mounting positions before assembly.

Flexible Graphics Card Presentation

Vertical mounting gives builders another way to display a powerful graphics card. The option should be compared with the card's cooler height, support bracket, and the final positioning of the side panel.

  • GPU clearance is below class leaders

We may earn a commission when you buy through this link, at no additional cost to you.

The product information states that the spacious chassis can hold up to three 360mm radiators simultaneously, with top and side positions identified for liquid-cooling use. Its vertical airflow design uses bottom and side intake areas, top and rear exhaust, and dust filters at both the top and bottom. Two tempered-glass panels create a panoramic 270-degree view of the internal hardware.

The headline radiator capacity should still be treated as a planning guide rather than a guarantee for every combination. Fans, fittings, pump housing, reservoir, tubing bends, and motherboard accessories all affect usable space. Graphics card clearance is 400mm, which is adequate for many modern cards but shorter than the H2 and DY470 can offer.

The H1 is a strong choice for builders who want a visually dramatic enclosure and several ARGB fans already in place. It is particularly useful for a mid-tower that can support several radiators without moving to a full tower. Confirm the exact mounting arrangement against the planned components before committing to a three-radiator configuration.

Seven Fans Simplify Initial Assembly

The preinstalled fans cover bottom intake, side intake, and rear exhaust positions. Daisy-chain wiring reduces the number of separate fan connections, while PWM and ARGB control remain available through compatible motherboard software.

Vertical Airflow and Dust Management

Bottom and side intakes feed cooler air into the main chamber, while top and rear locations act as exhaust. Removable dust filtering at the top and bottom helps limit particle accumulation around radiators and sensitive hardware.

We may earn a commission when you buy through this link, at no additional cost to you.

Cooling capacity extends to eleven 140mm fan positions through custom panel ventilation. A dedicated hybrid structure directs bottom intake toward the centrally positioned graphics card, addressing the common challenge of cooling a thick GPU in a dual-chamber design. The integrated PWM fan hub and simplified top-to-bottom cable guides help manage the wiring demands created by a large fan and radiator configuration.

This complexity is the main consideration. A three-radiator build leaves little room for improvisation, and the three-way adjustable GPU support bracket must be positioned carefully to avoid interference with tubing, fans, or the graphics card itself. The heat-formed curved glass and VESA portable-display mount add visual and functional flexibility, while rubber pads on fan brackets help reduce vibration transfer.

Choose the HS 420 for a showcase-grade custom loop where maximum radiator and fan capacity matters more than simplicity or minimal enclosure size. It is best suited to an experienced builder who can plan airflow, tubing routes, pump orientation, reservoir placement, and support hardware before the chassis is assembled.

Three 420mm Mounting Zones

Top, right, and bottom radiator positions make the HS 420 suitable for separate CPU and GPU loops. Every installation should be checked for tube routing, pump clearance, and the effect of adjacent fans on available radiator width.

Cable Management at Scale

The SimpliCable system uses grooved guides to create a continuous route from top to bottom. A PWM fan hub simplifies control for a large fan population, though physical cable volume still depends on the selected lighting and fan-control ecosystem.

The NZXT H6 is a compact ATX dual-chamber case with a 4.6 rating. It is designed for owners who want the H-series clean aesthetic and separated power chamber in a smaller enclosure. Angled front-right fans target the main components, while the dedicated secondary chamber keeps power supplies and cables away from the primary view.

Pros

  • Compact ATX dual-chamber design
  • Ten standardized fan mounts
  • Integrated GPU anti-sag bracket
  • Fine mesh across major panels
  • Removable bottom dust filter

Cons

  • No fans included

We may earn a commission when you buy through this link, at no additional cost to you.

The chassis provides ten standardized 120mm fan mounting locations across the top, front-right, bottom, and rear. Fans are not included, which gives buyers complete control over radiator thickness, fan performance, lighting, and budget. Ultra-fine mesh covers the top, front-right, and right panels, and a removable bottom nylon filter helps limit dust without restricting intake.

Because the case ships without fans, it is not the most convenient option for a first water-cooled build. A radiator and its fans must be selected and purchased separately, and the available fan positions must be reconciled with radiator dimensions. The integrated adjustable GPU anti-sag bracket is a notable convenience, although large graphics cards still require careful clearance checks.

The H6 makes the most sense for a compact, carefully planned build where visual minimalism and a clean cable-free motherboard layout are priorities. It is particularly attractive for builders using ASUS BTF or MSI Project Zero-style rear-connected motherboards. Choose a different case if preinstalled cooling hardware and immediate fan flexibility are more important.

A Deliberate Blank Canvas

Shipping without fans lets the owner choose fan sizes and control methods without replacing bundled components. This is useful for matching an established RGB or PWM ecosystem and for budgeting a specific cooling arrangement.

Compact With Purposeful Organization

The separated chamber protects the main build from power-supply heat and cable clutter, while angled airflow focuses on hot components. The fine panel mesh and removable filter support the compact enclosure's cooling strategy.

  • No anti-sag hardware mentioned

We may earn a commission when you buy through this link, at no additional cost to you.

Seven 120mm ARGB PWM fans are preinstalled, with six using reverse blades and one using a forward-blade design. The dual-chamber arrangement separates the power supply and drives from the main hardware, improving the visual organization and supporting thermal separation. The main chamber accepts ATX, M-ATX, and ITX motherboards, while graphics cards up to 400mm and power supplies up to 200mm fit.

The 400mm graphics card limit is shorter than the H2's 455mm allowance and the DY470's 410mm limit, so unusually long cards require close verification. No dedicated GPU anti-sag bracket is mentioned, and the three-radiator claim still depends on finding compatible space for the pump, reservoir, fittings, and tubing. A careful parts inventory remains essential.

The F600 is a good recommendation for a visually ambitious mid-tower that needs many radiator mounting points and already has substantial ARGB fan hardware. It is particularly attractive to builders who prefer a panoramic chamber view over a smaller footprint and are comfortable planning a dense custom-loop layout.

High Cooling Density in a Mid-Tower

Three 360mm positions allow substantial radiator area without moving to a full tower. The compact layout demands discipline, with each radiator thickness, fan stack, and tube bend included in the planning process.

ARGB Hardware Ready from the Start

Seven preinstalled PWM ARGB fans create an illuminated foundation and cover multiple intake and exhaust positions. Their reverse-blade placement helps preserve a clean visual orientation through the panoramic glass.

We may earn a commission when you buy through this link, at no additional cost to you.

The dual-chamber design includes an independently ventilated power-supply area, helping keep the secondary chamber separate from the primary hardware. Magnetic dust filters at the top and bottom help manage dust, and tool-free panel removal is intended to simplify installation. A Type-C connection and USB 3.0 are included among the front I/O options.

Compared with the H1, H2, F600, and HS 420, the Y6 offers much less multi-radiator expansion. Its 400mm GPU clearance is adequate for many cards but not the longest enthusiast models, and only three fans are included. Nevertheless, fewer preinstalled components can make the interior easier to understand and configure for a first custom loop.

Choose the Y6 for a straightforward, attractive dual-chamber system built around a single 360mm radiator. It is a sensible option for gamers and creators who value a clean 270-degree tempered-glass view, straightforward installation, and sufficient space for mainstream high-performance components without carrying the complexity of a multi-radiator chassis.

A Manageable First Water-Cooled Build

A 360mm radiator leaves more open space for pump, reservoir, and fittings than a densely packed multi-radiator arrangement. The simpler layout can be easier for first-time custom-loop builders to plan and assemble.

Filtered, Separated Airflow

The power supply receives its own ventilation channel, reducing its influence on the main chamber. Magnetic filters at the top and bottom can be removed for routine cleaning, helping preserve airflow as the system ages.

Six infinity-mirror PWM ARGB fans are preinstalled, with five using reverse blades and one using a forward-blade design. Their mirrored surfaces create a pronounced lighting effect through the transparent high-hardness tempered-glass panels. The A/B partition system organizes the power supply, drives, and cables in a separate area, with built-in anchor points for cleaner wiring.

The compact dimensions are the main reason to choose this case over the H1. A less tall chassis can fit beneath more desk layouts, but the reduced volume leaves less space for multiple radiators, reservoirs, or a broad collection of cable branches. The 4.0 rating is also the lowest in this comparison, so buyers should pay particular attention to current customer feedback and fitment details.

The H3 is best suited to a compact gaming or productivity system with a single 360mm radiator and a strong emphasis on mirrored RGB lighting. It is a sensible option when physical footprint matters more than maximum expansion. For larger custom loops, the taller H1 and H2 or the highly expandable HS 420 provide a better fit.

Compact Exterior, Expensive-Style Lighting

Infinity-mirror fans create a more dramatic visual effect than conventional diffuser fans. Their PWM control and ARGB lighting make the H3 appealing for builds where illumination is a central part of the design.

Organized Dual-Cavity Layout

The A/B partition separates cooling and computing hardware from the power supply and storage area. Anchor points help keep the limited cable space orderly, although a compact enclosure still requires disciplined cable routing.

Buying Guide – How to Choose the Best Dual Chamber PC Cases for Water Cooling

Choosing a dual chamber case for a custom loop means balancing radiator capacity against chassis size, component clearance, and build complexity. The following factors help narrow the field before a buyer commits to a platform.

Radiator Size and Mounting Locations

Radiator support is more meaningful when expressed as both a maximum size and a list of usable positions. A 420mm rating indicates that a large premium radiator can fit, while top, front, side, and bottom positions reveal how many cooling zones the chassis actually offers. Multi-radiator support can improve thermal headroom, but it also reduces space for the pump, reservoir, fittings, and tubing.

Fan Orientation and Included Hardware

Fans determine whether air actually moves through each radiator. The H9 Flow uses angled front-right fans, while several other cases use conventional bottom, side, rear, and top arrangements. Check whether the included fans are PWM or basic case-version models, whether reverse blades are used for visual alignment, and whether a hub or controller is included.

Motherboard and Rear-Connector Support

Most cases support ATX, Micro-ATX, and Mini-ITX, but E-ATX support can be useful for workstation boards and extensive expansion. Hidden-connector or rear-connect motherboard support removes most cables from the visible chamber. This works especially well with compatible ASUS BTF and MSI Project Zero boards, although it should not be assumed for every motherboard model.

Graphics Card Clearance

Modern graphics cards vary considerably in length, thickness, power demand, and cooler height. A 400mm allowance covers many mainstream cards, while the H2 reaches 455mm and the DY470 reaches 410mm. Length alone is not enough: builders should also inspect the side-panel clearance, fan thickness, support bracket, tubing path, and the position of any vertical GPU mount.

Dual-Chamber Airflow Separation

The purpose of a dual chamber is to isolate the power supply, storage, and wiring from the main computing and graphics area. This can improve heat organization and reduce visual clutter. The HAVN HS 420 adds a hybrid approach that directs bottom intake toward the GPU, while other cases rely more heavily on conventional front or side intake.

Cable Routing and Hidden Cables

A water-cooled build can require cables for pumps, fans, RGB lighting, power, and data. Velcro straps, tie-down points, grooved channels, and wide spaces behind the motherboard tray make routing easier. The NZXT H9 and H6 support rear-connected motherboards, while the H2, H1, and H3 describe dedicated straps or partition-based cable systems.

Reservoir, Pump, and Tubing Space

Radiator support does not account for every part of a custom loop. A pump needs a secure mounting area, a reservoir needs clearance for fluid and tubing, and hard or soft tubes need enough bend radius to avoid kinks and excessive stress. The compartment behind the motherboard or under the radiator shelf may be as important as the visible main chamber.

Exterior Size and Aesthetics

The cases range from the compact NZXT H6 to full-size mid towers and the darkFlash DY470 full tower. A smaller case can save desk space but reduce radiator options, while a larger chassis offers more cooling and reservoir space. Tempered-glass panels, steel mesh, curved glass, infinity mirrors, and ARGB fans all influence the final appearance, but lighting should be considered alongside airflow and maintenance access.

How to Use and Care for Your Dual Chamber PC Cases for Water Cooling

Begin by planning the entire loop on paper before installing any hardware. Identify the CPU and GPU radiator assignments, mark every mounting point, and route both pump power and lighting connections before panels are attached. Confirm that the motherboard, graphics card, memory, reservoir, and fittings can all coexist without blocking service access.

Install the case fans and radiators with the correct airflow direction, then connect the pump and test the system before adding coolant. Watch pump startup, tubing, fittings, and the CPU temperature under a controlled load. A leak check performed before the system is hidden behind panels makes troubleshooting considerably easier and protects nearby components.

Keep the dust filters clean, inspect the radiator and fan surfaces periodically, and verify that all connectors remain firmly seated. Avoid routing sharp tubing bends against fan frames or moving parts, and check the system for condensation, unusual pump noise, or rising temperatures. For custom loops, follow the pump and coolant manufacturer's guidance and service the liquid at the intervals they recommend.

Frequently Asked Questions

What is the main advantage of a dual chamber PC case?

A dual chamber separates the power supply, drives, and some wiring from the main motherboard, graphics card, and cooling area. This can make airflow more focused, improve the appearance of the build, and provide additional routing space. Actual thermal performance still depends on the overall fan and radiator arrangement.

Are dual chamber cases better for water cooling?

They can be better for builds that need organized cables, substantial radiator support, and airflow aimed at the CPU and GPU. However, a dual chamber does not automatically produce better temperatures. A correctly configured conventional case with a large radiator and suitable fans can cool effectively.

Can I install a 420mm radiator in every case listed?

No. The H2, NZXT H9 Flow, and HAVN HS 420 explicitly support 420mm radiators, while the other listed models state support up to 360mm. Check the exact mounting location as well, since case dimensions, fans, tubing, and motherboard accessories can reduce the usable radiator width.

Do I need to buy extra fans for a custom water loop?

That depends on the chosen case and loop design. The H2, H1, and F600 include substantial fan bundles, while the NZXT H6 ships without fans. Even when fans are included, a dedicated radiator often requires a specific count and orientation. Always check the mounting pattern, connector type, and available controller or hub.

What motherboard size should a dual chamber case support?

Most models support ATX, Micro-ATX, and Mini-ITX, while the larger H2 also lists E-ATX support. A case listing a standard form factor does not guarantee that every board fits with large RAM modules, tall CPU coolers, rear connectors, or a vertical graphics card, so compare the complete board outline and accessory clearances.

Are rear-connect motherboards useful with a dual chamber?

They can be extremely useful because they move many power and data connections behind the motherboard tray. The NZXT H9 Flow and H6 explicitly support compatible rear-connected boards, while the Thermaltake View 380 and HYXN H3 also list hidden-connector or rear-mounted motherboard compatibility. The exact board and case versions must be verified before purchase.

How do I know if my graphics card will fit?

Compare the card's exact length, height, slot width, cooler overhang, and power-connector position with the case specification. The listed limits range from 400mm to 455mm, but water-cooling builds also need room for side fans, tubing, and a support bracket. Measure the assembled cooler and cable arrangement whenever possible.

Should I clean the dust filters in a dual chamber case?

Yes, routine filter cleaning helps maintain the intake path and reduce dust on radiators, fans, and heatsinks. The H1 and Y6 use top and bottom filters, the H6 has a removable bottom nylon filter, and the DY470 includes a bottom dust filter. Check filters more often in dusty environments or when temperatures gradually rise.

Final Thoughts on Choosing the Best Dual Chamber PC Cases for Water Cooling

The NZXT H9 Flow RGB is the strongest all-around choice because it combines 420mm radiator positions, good airflow design, integrated RGB hardware, and refined cable management. The Thermaltake View 380 TG ARGB is the best budget starting point, while the HAVN HS 420 is the premium selection for builders intending to install an elaborate three-radiator cooling system.

Prioritize radiator locations, fan direction, pump and reservoir space, graphics card clearance, and the actual complexity of the planned loop. A case with more advertised capacity is not automatically better if the tubes cannot bend cleanly or if daily maintenance becomes difficult. Match the chassis to the cooling ambition instead of choosing the largest specification on paper.

Ratings, product revisions, and prices can change, so verify the current listing and dimensions before ordering. Confirm the motherboard format, rear-connector arrangement, graphics card measurements, radiator width, and tube paths. With that final compatibility check completed, the right dual chamber case can provide both a polished appearance and a well-organized foundation for water cooling.
