AI Verdict
This is a large ATX mid-tower case with an octagonal design, 420mm radiator support, and hidden connector motherboard compatibility, built for showcasing high-end components.
This case is a strong fit for builders focused on high-performance ATX systems with extensive cooling, especially liquid cooling, and those who value a clean aesthetic with hidden connector motherboard support. Its 400mm GPU clearance and 420mm radiator support are top-tier for a mid-tower.
If you need even more radiator thickness or space for multiple custom loops, look for full-tower cases with dedicated pump/reservoir mounting points.

Pros
- Accommodates GPUs up to 400mm in length without the power cover, allowing for large graphics cards.
- Supports up to a 420mm radiator on the right side and a 360mm radiator on the left side for extensive liquid cooling setups.
- Features extra cutouts for ATX hidden connector motherboards (like ASUS BTF, MSI PROJECT ZERO, GIGABYTE PROJECT STEALTH) for cleaner cable routing.
- Includes 1x USB-C 3.2 Gen 2 (10 Gb/s) and 4x USB-A 3.2 Gen 1 (5 Gb/s) ports on the front panel for fast connectivity.
- Offers a tool-free, fully dismantlable design with magnetic dust filters for easy access and maintenance.
- Provides flexible fan support for up to nine 140mm fans or thirteen 120mm fans for optimized airflow.
Cons
- The case is physically large, measuring 550 x 420 x 286.4 mm, making it a significant footprint on a desk.
- GPU clearance reduces to 281mm if the left PSU cover is installed, potentially limiting some larger GPUs.
- The 420mm radiator support on the right side is effectively limited to slim 30mm thick radiators, restricting options for thicker units.
- Rear fan mounts attach directly to the back panel, making it difficult to remove the panel once fans are installed and cabled.
- EPS cables can be tight with custom sleeved cables, with stock flat cables fitting better.
Dimension Scores
The case supports up to a 420mm radiator and thirteen 120mm fans, providing substantial cooling potential for high-performance components.
It includes two 140mm CT fans, which are generally quieter than smaller fans, but the overall noise will depend heavily on the total fan configuration and component choices.
Constructed from SPCC steel and featuring three 3mm tempered glass panels, the case feels sturdy and well-made.
The case offers a spacious interior with two sets of cable clips, Velcro straps, and support for hidden connector motherboards, making cable routing cleaner.
Best For
- Builders planning custom liquid cooling loops with large radiators.
- Showcasing high-end components with its three tempered glass panels and vertical layout.
- Utilizing hidden connector motherboards for an exceptionally clean, cable-free aesthetic.
- Enthusiasts who prioritize maximum airflow and fan capacity.
Not Recommended For
- Users with limited desk space due to its substantial dimensions.
- Budget-conscious builders, as its mid-range price point and specialized features might be overkill.
- Anyone needing to frequently access the rear panel after installing rear fans.
Watch Out For
- The 420mm radiator spot on the right side only fits slim 30mm thick radiators, so don't plan on a thick rad there.
- If you're using a large GPU, you might have to remove the left PSU cover, dropping GPU clearance from 400mm to 281mm.
- Installing fans on the rear panel makes it a pain to remove that panel later because the fans attach directly to it.
- Custom sleeved EPS cables can be a tight fit, so you might need to stick with stock flat cables for easier routing.

What Buyers Say
This case is a beast, physically huge, which is the first thing you'll notice when it arrives. People are really into its unique octagonal look and the ability to show off their build through the three tempered glass panels. The support for hidden connector motherboards is a big win for clean builds, but watch out for radiator thickness on the right side, as it's limited to slim 30mm units for 420mm rads. Also, if you plan on using rear fans, know that removing the back panel later will be a hassle.
“Man, this case is HUGE, but my RTX 4090 and 420mm AIO fit like a glove, and my cables are practically invisible with my BTF board, totally worth the desk space!”
Common Praise
- The octagonal design and three tempered glass panels make the build look really sharp.
- Plenty of room for large GPUs up to 400mm, which is great for high-end cards.
- Excellent support for liquid cooling, especially with the 420mm radiator capacity.
- Compatibility with hidden connector motherboards helps achieve super clean cable management.
- The tool-free design for panels and overall modularity makes building and maintenance easier.
Common Complaints
- The case is genuinely massive, taking up a lot of desk space.
- The 420mm radiator mount on the right side is only compatible with slim 30mm radiators, limiting options.
- Installing fans on the rear panel makes subsequent removal of that panel inconvenient.
- EPS cables can be a tight squeeze with custom sleeved cables.
- GPU clearance drops significantly to 281mm if the left PSU cover is kept installed.
Ownership Tips
- You'll need to plan your radiator choices carefully; that 420mm spot on the right really does only take slim ones.
- The weight of this thing fully built is no joke, so make sure your desk can handle it.
- The magnetic dust filters are a blessing for cleaning, but they do need regular attention.
- The vertical layout means your GPU is really on display, so make sure it looks good.
- If you're going for a truly clean look, the hidden connector motherboard support is a game-changer, but it's a specific type of board you need.

Buying Guide
When you're looking at a case like this, you're not just buying a box for your parts; you're buying a display piece and a cooling powerhouse. You need to think about how much space you actually have, because this case is big. Also, consider your cooling plans: are you going air or liquid? This case leans heavily into liquid cooling with its radiator support.
420mm Radiator Support
This means the case can fit a very large liquid cooling radiator, which is crucial for keeping high-performance CPUs and GPUs cool, especially if you're overclocking. Think of it like a bigger, more efficient car radiator for your PC.
400mm GPU Clearance
This measurement tells you the maximum length of a graphics card that will fit inside. Modern, powerful GPUs can be very long, so a high clearance number means you won't have to worry about your dream graphics card being too big for the case.
Hidden Connector Support
This refers to compatibility with special motherboards that have their power and data connectors on the back. It's a big deal for aesthetics, as it allows you to hide almost all cables behind the motherboard tray, making your build look incredibly clean, like a perfectly organized closet.
Alternatives
If this case is too large or you don't need extensive liquid cooling, look for smaller mid-tower cases with less radiator capacity, or if you need even more space for custom loops, search for full-tower cases with greater internal volume.
