Cons
- At 17.84 kg and 541 x 259.5 x 547 mm, this case is quite large and heavy, making it less portable.
- Mounting 420mm radiators at the top can be tight, especially near motherboard VRMs, potentially complicating installation.
- E-ATX motherboards wider than 277mm might overlap cable management cutouts, leading to a messy appearance.
- The bottom intake for fans might be somewhat restricted, potentially starving airflow if relying solely on it for updraft systems.
Dimension Scores
The case supports eleven 140mm fans and three 420mm radiators, providing exceptional cooling potential for high-output systems.

What Buyers Say
The most surprising feedback is how much users appreciate the cable management, with one Reddit user calling it the "best designed" they've ever seen, even compared to cases like the Lian Li O11 Dynamic XL. The UniSheet curved glass panel is also a standout, praised for its seamless look and easy removal. However, the sheer size and weight of the case are frequently mentioned, with the empty chassis alone weighing 17.84 kg. Some builders also noted potential clearance issues with 420mm radiators at the top, especially around motherboard VRMs.
“Dude, this case is a tank, but the cable routing is actually insane, like I finally have a clean build and that curved glass is just chef's kiss, even if my back hates me for moving it.”
Common Praise
- The one-piece curved glass panel is easy to remove and reattach, eliminating gaps.
- Cable management system is thoughtfully designed with intentional wire channels and holes.
- The overall build quality feels solid, with no cheap-feeling components.
- Excellent airflow and thermal performance, especially for the GPU with its targeted cooling.
- The case offers a spacious interior, making it pleasant to build in.
Common Complaints
- The case is very heavy, weighing 17.84 kg empty.
- Mounting 420mm radiators at the top can be tight due to proximity to motherboard VRMs.
- E-ATX motherboards wider than 277mm can overlap cable management cutouts.
- Bottom intake airflow might be somewhat restricted, potentially starving fans.
Ownership Tips
- The dual-chamber design truly helps with GPU temperatures, keeping my RTX 4090 cooler than my previous case.
- The integrated fan hub is a lifesaver for managing all the 140mm fans without needing extra controllers.
- Dust accumulation on the bottom intake filter is noticeable, requiring regular cleaning to maintain airflow.
- The sheer size means it dominates my desk, so measure your space before committing.

Buying Guide
When you're looking at PC cases, especially mid-towers like this, you need to think about what you're actually putting inside. Don't just pick one because it looks cool. Consider how many fans and radiators you'll use, what size your motherboard is, and if your massive graphics card will fit and stay cool. Cable management isn't just for looks; it helps with airflow too.
Dual-Chamber Design
This isn't just a fancy term; it separates the hot components (like your GPU and CPU) from the power supply and drives. This means better, more directed airflow to the parts that generate the most heat, like having a dedicated AC unit for your graphics card.
420mm Radiator Support
A 420mm radiator is huge, and supporting three of them means you can run some serious liquid cooling. If you're planning on overclocking or running a very hot CPU and GPU, this is how you keep things frosty, like having a commercial-grade freezer for your PC.
SimpliCable Cable Management
Messy cables block airflow and look terrible. A good cable management system, like this one with its grooved guides and fan hub, makes building easier and keeps your PC looking clean and performing better, like having a perfectly organized toolbox where everything has its place.
UniSheet Tempered Glass
This isn't just any glass panel. It's a single, curved piece that gives you an unobstructed view of your components without distracting seams. It's like having a panoramic window into your PC, showing off all your expensive parts.
Alternatives
If this case is too large or heavy, look for mid-tower cases with a more traditional single-chamber design and support for smaller 240mm or 360mm radiators. If you need more E-ATX compatibility, search for cases explicitly stating full E-ATX support without cable cutout interference.
