3. The case utilizes OCuLink for improved bandwidth between components, featuring a simple two-piece design made from heat-resistant ASA filament.
4. Cooling is managed by a quiet 120 mm fan, maintaining optimal temperatures during gaming sessions, while power management is streamlined.
5. Performance tests show the setup delivering desktop-level gaming with high FPS in popular titles like Red Dead Redemption 2 and God of War Ragnarök, aimed at DIY and gaming enthusiasts.
YouTube channel ITG Gear has introduced a small, 3D-printed gaming case that rethinks the Steam Machine idea by utilizing current mini PC components and a connection for an external GPU.
The ITG Cube Design
Called the “ITG Cube,” this creation by the modder features a cube-shaped design that is intended to hold an Aoostar GEM12 MAX mini PC. It’s powered by an AMD Ryzen 7 8745HS with a Radeon 780M integrated GPU. This setup is available on Amazon for $289. Additionally, it features a compact cooling solution and a low-profile single-fan HP RTX 4060, which can be found on eBay for $239.95, along with an OCuLink-based eGPU dock, all fitting within a small 165 × 165 × 165 mm size.
Innovative Connectivity Choices
Instead of using USB4 or Thunderbolt, the builder chose OCuLink to provide better bandwidth between the mini PC and the graphics card. The entire enclosure is 3D printed and consists of just two main pieces, making the assembly process fairly simple.
The case was made with heat-resistant ASA filament and includes integrated rails, which allow the mini PC, GPU dock, and cooling system to slide into position without needing complicated mounting tools.
Efficient Cooling and Performance
Cooling is managed by a sizable 120 mm fan located on the top. Although the fan is powered through USB instead of full PWM control, the creator mentions that it operates quietly while maintaining temperature during long gaming periods. Power management and cable organization are also kept simple, with the eGPU aligning power states directly with the mini PC.
In the gaming tests presented in the video, the setup exhibits desktop-level performance at 1200p, achieving an average of 105 FPS in Red Dead Redemption 2 with a combination of high and ultra settings. During gameplay, it shows the CPU running at about 59 °C, while the RTX 4060 GPU stays around 74 °C.
Game Performance Benchmarks
The modder also evaluated God of War Ragnarök, which ran at roughly 100 FPS, Doom: The Dark Ages, which ranged from 75 to 90 FPS, and Cyberpunk 2077, which averaged about 95 FPS under similar settings.
The video promotes the ITG Cube as a concept for the DIY and gaming enthusiasts rather than a product for sale. Complete build details and design files are shared in the full video.
