- Supports 360mm AIO radiators on the right side, providing extensive liquid cooling options for a Mini-ITX chassis.
- Features a compact vertical design, measuring 506mm tall, 300mm wide, and 281mm deep, saving desk space.
- Includes two 120mm CT fans pre-installed at the top for exhaust, with support for up to eight 120mm fans total.
- Offers tool-free panel removal and a removable side radiator bracket, simplifying component installation and maintenance.
- Provides a USB 3.2 Gen2 Type-C port and two USB 3.0 Type-A ports on the top-mounted front I/O for modern connectivity.
Cons
- One user reported overheating with long GPUs due to heat pipe orientation when the card is mounted upside down.
- Only provides three expansion slots, which might limit multi-card setups or specific expansion needs.
- Despite cable routing space, a reviewer noted a large bundle of wires can be visible in an open area.
- The optional 3.9-inch LCD screen and chassis stand kit are sold separately, increasing the total cost for full functionality.
Dimension Scores
The case supports 360mm radiators and up to eight 120mm fans, indicating strong potential for thermal management in a compact form factor.
The two included CT120 fans operate at 2000rpm with a reported noise level of 25.8 dBA, which is average for stock fans.
Constructed from alloy steel (SPCC) with three 3mm tempered glass panels, suggesting a sturdy build.
There is space behind the motherboard tray for cable routing, but a reviewer noted a large bundle of wires can be visible in an open area.
Best For
- Compact gaming setups needing high-end GPU and AIO liquid cooling support.
- Desk setups where vertical orientation and a small footprint are priorities.
- Builders who prioritize easy access for component installation and cleaning.
Not Recommended For
- Users planning multi-GPU configurations due to three expansion slots.
- Budget-conscious buyers who want all features included without additional purchases for accessories.
Watch Out For
- A user experienced a 5090 GPU overheating instantly under minor load due to the upside-down mounting orientation affecting heat pipe function.
- The case has three 3mm tempered glass panels, which increases its 7.1 kg weight and potential for breakage.
- While supporting ATX PSUs up to 200mm, using a larger PSU might restrict airflow in the bottom chamber if not SFX.
- The case's vertical design means the I/O faces upwards, which might not suit all desk configurations.

What Buyers Say
One significant concern raised by a user is the potential for overheating with longer GPUs, specifically a 5090, when mounted in the case, suggesting an issue with heat pipe orientation in the vertical setup. Despite this, the case is frequently highlighted for its ability to house large components like 360mm GPUs and radiators within its compact Mini-ITX footprint. The tool-free panel removal and removable radiator bracket are often mentioned as features that simplify the building process. The inclusion of a USB-C port on the front I/O is also a recurring positive point for modern connectivity.
“Dude, this case looks sick on my desk, but my 5090 got super hot, like instantly, when I tried to game, gotta figure out that GPU orientation thing.”
Common Praise
- Accommodates a 360mm AIO radiator on the right side, which is uncommon for Mini-ITX cases.
- Fits GPUs up to 360mm in length, allowing for high-performance graphics cards.
- The vertical, octagonal design offers a unique aesthetic and saves desk space.
- Tool-free panel removal makes accessing components and building inside the case easier.
- Front I/O includes a USB 3.2 Gen2 Type-C port, providing fast data transfer.
- Supports both ATX and SFX power supplies up to 200mm, offering flexibility.
Common Complaints
- A 5090 GPU overheated due to its heat pipes not functioning correctly when mounted upside down.
- Cable management, while present, can result in a visible bundle of wires in an open section of the case.
- The optional LCD screen and horizontal stand are separate purchases, adding to the cost.
- Limited to three expansion slots, which restricts certain hardware configurations.
Ownership Tips
- The vertical design with glass panels means dust can settle visibly, requiring frequent cleaning of the filters.
- The upward-facing I/O ports can be convenient but might require specific cable routing depending on desk setup.
- The dual-chamber layout helps separate heat sources, but careful fan placement is still crucial for optimal temperatures.
- The case's weight of 7.1 kg, combined with components, makes it less portable than some other Mini-ITX options.
Frequently Asked Questions

Buying Guide
When looking at a Mini-ITX case like this, you need to think about how much space you actually have on your desk and what kind of power you want to cram into it. This isn't a tiny shoebox; it's a vertical tower that still takes up a fair bit of height. Make sure your chosen CPU cooler and GPU will physically fit, and consider how you'll manage the heat from those components in such a confined space.
360mm Radiator Support
This means you can install a large liquid cooler, which is crucial for keeping high-performance CPUs cool in a small case, preventing your system from throttling under heavy load.
360mm GPU Clearance
This measurement tells you the maximum length of a graphics card you can install. Many top-tier GPUs are quite long, so this clearance ensures you can use powerful cards without needing to downsize.
Dual Chamber Design
This separates heat-generating components like the power supply and storage drives from the main motherboard and GPU area. It helps with airflow and can make cable management easier by hiding bulkier cables.
Alternatives
If you need more expansion slots or prefer a smaller footprint for a Mini-ITX build, look for cases with a more traditional horizontal layout or those that prioritize extreme compactness over large component support.
