Ultra-low power gaming rig

This unique build pairs the Palit GeForce RTX 3050 KalmX graphics card and the i3-N305-powered ODROID H4 Ultra in a 3.5L case. Additional components include the ADT-Link eGPU adapter and the fanless HDPLEX 250W pico PSU. Performance is surprisingly good: "I'm able to run Resident Evil 2 Remake at over 60fps with no issues, while just sipping power."
