• Features Extreme Radiator Support Designed for serious cooling headroom with support to ensure practical usability across varied workspace setups.
• Built to maintain consistent operational stability within standard product design conditions.
• Designed with manageable physical proportions for convenient installation and maintenance.

Following standard operation guidelines and maintaining adequate surrounding clearance ensures optimal functional longevity.

This is a full E-ATX chassis, and the clearance figures are what justify the footprint it takes up.

• Graphics cards up to 400mm long and 190mm wide, which covers the largest triple-slot RTX 40 series boards
• 180mm of CPU cooler height, enough for any air tower currently sold
• 360mm radiators mount at both the front and the top
• Vertical GPU mounting is supported, though the riser cable is a separate item

Motherboard support runs from Mini-ITX up to E-ATX, so this is a case you can move a future full-size board into rather than replacing the chassis alongside it. Tempered glass forms the side panel, giving a clear view of the lit interior and the cooling hardware behind it.

Four 140mm PWM fans come preinstalled: three ARGB units at the front intake and one at the rear exhaust, wired into an LED and PWM controller carrying 21 lighting effects.

• The metal front panel is engineered for a 51% ventilation rate, unusually open for a solid-looking face
• 140mm fans move more air per revolution than 120mm units, so the same airflow arrives at a lower speed and less noise
• The mesh front doubles as the dust filter and pulls off without tools for cleaning

Positive pressure from three intakes against a single exhaust keeps dust travelling through the filter rather than in through panel seams. Cleaning that filter every couple of months is effectively the only routine maintenance the case needs.

The front I/O includes a USB-C port alongside the usual USB-A and audio jacks, so a modern motherboard header is not left unused.

• Fan and lighting control run through the bundled LED and PWM controller, so an ARGB motherboard header is optional rather than required
• Tempered glass adds mass, so support the panel with both hands when removing it and move a completed build with the glass side facing up
• The full E-ATX footprint needs floor or desk space and will not slide under a shallow desk shelf

This SKU is listed in black only. For a first build, the open interior and generous clearances make cable routing and cooler fitting noticeably less awkward than working inside a compact chassis.

The Vector V100 comes with 4 pre-installed 120mm ARGB PWM fans using hydraulic bearings, each capable of up to 1800 RPM, 61.47-60.4 CFM airflow, and 2.54-2.17 mm-H2O air pressure, with noise ranging 26.5-30.8 dBA depending on speed. A 26-LED ARGB strip adds further lighting, and both fans and strip daisy-chain together for a simpler cable run than wiring each component separately.

• 4x 120mm ARGB PWM fans included, hydraulic bearing design
• 26-LED ARGB strip with full spectrum color control
• Daisy-chain connectivity reduces individual cable runs

Fan and strip lighting sync with motherboard ARGB software, so color and effects can match other components already running compatible lighting ecosystems.

The case supports ATX, Micro-ATX, Mini-ITX, and back-connect ATX or Micro-ATX motherboards, giving builders the option of a standard layout or a back-connect board for hidden cable routing behind the tray. Tool-less mounting on each side panel speeds up the build process, since panels come off without reaching for a screwdriver for routine access.

• Back-connect motherboard support for cleaner cable management
• Tool-less side panel mounting mechanism
• Included GPU support bracket for heavier graphics cards

E-ATX and other oversized motherboard formats are not on the supported list, so builders working with larger boards will need to confirm fit before assembling the rest of the build.

Internal clearance is built for high-end hardware: graphics cards up to 420mm, CPU air coolers up to 178mm tall, and a top-mounted radiator up to 360mm. That headroom leaves room to move from air cooling to a 360mm liquid loop, or to swap in a longer flagship GPU later, without the case itself becoming the limiting factor.

• 420mm max GPU length clearance
• 178mm max CPU cooler height
• 360mm top radiator support

A GPU support bracket is included to help offset the weight of longer graphics cards over time, reducing sag as heavier cards are installed.

The Okinos Genuine Walnut Wood PC Case Support 360mm provides essential hardware performance for custom PC builds and workstation upgrades. Engineered to manage demanding electrical or thermal workloads, this model incorporates Genuine Walnut Wood Fusion with High Performance Chassis Combines together with Pre-installed with 4 PWM fan Through pre-installed fans, airflow intake.

Three 120 mm addressable PWM fans ship pre-installed behind a perforated steel front panel. The perforation uses a three-dimensional Y pattern designed to give air a low-obstruction path rather than forcing it through a flat mesh grille.

• Front rails take fans up to 200 mm
• Roof rails take fans up to 140 mm
• Side mounting available once the inner panel is removed
• Fans support a Zero RPM mode for near-silent behaviour at low load

The rail system is the useful part. Rather than fixed screw holes, the rails let you slide a fan to sit exactly over a graphics card or a radiator inlet. If you are running a high-power card, adding a rear exhaust fan is the first upgrade worth making, since all three included fans are intake.

This is a mid-tower ATX chassis built from alloy steel with aluminium elements, sized for a mainstream tower build rather than an extended workstation board.

• Supports ATX, micro ATX and mini ITX boards
• Supports rear-connector boards: ASUS BTF, MSI Project Zero, Gigabyte Stealth
• Roof radiator mounting up to 140 mm fan sizes
• The internal side panel doubles as a cable cover or a fan mount

Back-connect board support is the detail worth flagging. Those boards move every connector to the rear of the tray, which needs matching pass-through cut-outs in the case to work at all. If you are planning that style of build, this chassis is already prepared for it. For a conventional board, the same cut-outs simply serve as generous cable routing.

The distinguishing idea here is a chassis assembled from replaceable sections rather than a single riveted shell. Panels, the board tray and the front input panel are designed to come off and be swapped for alternatives.

• The motherboard tray can be exchanged for a billet aluminium version
• The front input panel can be swapped for one with a different port arrangement
• Side panels and rails come apart for access during a build

Two things follow from that. Building is easier, because you can strip the case back to a skeleton and reassemble around the components. And the case can change later without being replaced. The trade is that every alternative module is bought separately, so the version in the box is what you get until you choose to add to it.

The MONTECH XR Panoramic High Airflow ATX PC Case 3 ARGB PWM provides essential hardware performance for custom PC builds and workstation upgrades. Engineered to manage demanding electrical or thermal workloads, this model incorporates Experience mature wood grain design I O interface, seamlessly blending together with Accommodates a 360mm radiator at the top and supports high-end GPUs.

At 17.4 x 7.63 x 12 inches, the A3-mATX packs a 26.3 liter volume that still clears graphics cards up to 415mm long. Steel mesh panels on the side and top are designed specifically to move air through high-TDP GPUs and radiator setups rather than trap heat inside a closed shell.

• 26.3 liter internal volume in a compact mATX/ITX footprint
• GPU clearance up to 415mm, enough for most full-size graphics cards
• Mesh side and top panels prioritize airflow over a fully enclosed look

The compact size makes it a strong fit for small-form-factor builds that still need room for high-end hardware, rather than a true mini-ITX-only chassis.

The chassis accepts mATX and ITX motherboards across 4 expansion slots, and supports front or side PSU mounting compatible with ATX, SFX, SFX-L and LIAN LI's own EDGE power supplies. This flexibility lets builders orient the power supply to whichever side offers better cable routing for their layout.

• mATX and ITX motherboard support across 4 expansion slots
• Front or side PSU installation compatible with ATX, SFX, SFX-L and EDGE units
• Modular internal layout supports repositioning parts as the build evolves

Full ATX motherboards are not supported given the 4-slot limit, so builders should confirm their board size before purchase.

The case supports a 360mm radiator alongside up to 10 individual 120mm fans, giving serious headroom for liquid cooling in a small chassis. No fans are included, so cooling has to be assembled separately to match the intended thermal load.

• 360mm radiator support for all-in-one liquid coolers
• Up to 10 x 120mm fan mounting points across the chassis
• No fans included, plan to add case fans or an AIO separately

The walnut wood front panel and modular structure are built for builders who plan to revisit the internal layout over time, rather than a fixed one-time build, making later upgrades more straightforward than in a rigid steel-only case.

The PA602 pairs a 15.5mm open front grill at 45% porosity with dual 200 x 38mm front fans and a 140mm rear exhaust fan for a low-resistance intake path. Two internal air deflectors redirect incoming air toward the motherboard and other heat-generating components rather than letting it escape unused.

• Front fans: two 200 x 38mm, extra-thick for maximum intake
• Rear fan: 140 x 28mm exhaust
• Radiator support: up to 420mm for AIO or custom loops

A front panel IR dust indicator reminds the owner when the intake filter needs cleaning to keep airflow at its rated level.

Case dimensions run 23.35"D x 9.65"W x 22.05"H, built to fit E-ATX motherboards along with the largest current graphics cards. A dedicated GPU holder supports heavy cards either horizontally or vertically, and tool-less PCIe mounting means expansion cards click into place without a screwdriver.

• Board support: E-ATX and smaller form factors
• GPU clearance: ample room for full-length cards, horizontal or vertical
• Materials: alloy steel, plastic and tempered glass construction

A dedicated Wi-Fi antenna compartment keeps external antennas tidy without cluttering the rear I/O panel.

Front I/O includes a 20Gbps USB-C port alongside a Power Lock Latch and 2-section PWM fan control, giving builders headroom to add fans or an AIO cooler later without rewiring the whole case. The built-in fan hub centralizes PWM connections for easier expansion.

• USB-C: 20Gbps front-panel port
• Fan hub: built-in PWM management for future fan additions
• Warranty: 2 years from ASUS

Because the chassis already supports a 420mm radiator and multiple fan positions, most cooling upgrades can be added later without swapping the case itself.

The GT502 measures 17.56 inches deep by 11.22 inches wide by 17.72 inches tall, a full-tower footprint built to hold larger motherboards and extended cooling setups compared to a standard mid-tower case. Front panel connectivity includes USB 3.2 Gen 2 Type-C plus two USB 3.0 ports alongside an RGB lighting control button, positioned for easy reach without needing to access the rear I/O panel for common peripherals. Tempered glass panels sit at both the front and side of the case for a view into the main chamber, and tool-free side panels remove by pressing a button hidden on the rear of the chassis rather than requiring a screwdriver for routine access. The dual-chamber internal layout splits the main compartment from a rear chamber used for cable routing and additional components.

This case supports up to 360mm radiators in three separate locations: the rear chamber, the top of the case, and the right side, giving flexibility to place a large all-in-one liquid cooler wherever airflow and cable routing work best for a given build. Total fan capacity reaches up to 13 units across both chambers for builds prioritizing maximum airflow over quiet running. Graphics card mounting supports two orientations: a traditional horizontal slot directly into the motherboard, or a vertical mount using the included bracket, though the vertical option needs a separately purchased PCIe extension cable, which is not bundled in the box. A hybrid bracket in the rear chamber can alternatively hold up to three storage devices instead of a radiator, for builds that need more drive bays than cooling hardware.

The dual-chamber design gives builders room to separate CPU and GPU cooling zones, useful for anyone planning independent liquid loops or wanting the PSU and cabling fully out of view in the main chamber behind the tempered glass panel. Because the case supports radiators up to 360mm in three positions and as many as 13 fans, there is meaningful room to expand cooling later without switching to a different case if a build starts with air cooling and later moves to liquid. ASUS backs the GT502 with a 2-year warranty covering the case itself. The main tradeoff for all this flexibility is size: a full-tower footprint this large needs a dedicated spot in a room, so it suits a stationary desktop build rather than one moved often between locations.
