In this video, I design a custom Mini-ITX case with only 7.8L to accommodate a full-size RX 9060 XT 16GB GPU and a top-mounted case fan. The result? Impressive. CPU and GPU temperatures are so good, and gameplay at 1440p High settings is possible. Can this build be a console killer? Let's find out.

I walk you through the entire 3D-designed enclosure project, demonstrating how I optimized the internal airflow to keep the CPU at 65°C and the GPU at a cool 71°C during intense gaming and FurMark stress tests. This ultra-compact 3D-printed gaming PC delivers high-performance native 1440p gameplay in titles like God of War Ragnarok and Resident Evil Requiem, maintaining silent acoustics that are quieter than a mouse click. Whether you are looking for the ultimate console killer or a portable workstation for 3D modeling and content creation, this DIY 7.8L custom design proves that you can fit powerful PCIe Gen 5 hardware into a tiny footprint without thermal throttling or loud fan noise. Join me as I benchmark the RDNA 4 architecture in this unique handmade enclosure and see if this sub-8L masterpiece is the perfect solution for SFF enthusiasts and PC modders alike.
