With the board, power supply, m.2 and case filament for the print I’m in this build about $230.
Modded bios, lets you use the 16gb gddr6 In a free flowing on demand state from the cpu and gpu, has an m.2 port and uses a standard 8pin pcie for power. Jumped motherboard 24pin connector pins and wired to power button. USB 3.0 hub on the front (wired from the back) with 3pc 90 degree adapters and a bracket to hold them down.
Case Fits the bitcoin mining board, flex atx power supply, and a shroud/plate for a 120mm fan, blowing straight onto the hestsink. (Modification has to be done, two of the top sections of the cooler need to be opened up but the temps dropped substantially)
Running bazzite/steam OS setup and it games wonderfully. Forza horizon 5 1440p medium/high over 70 fps with fsr, 1440p marvel rivals medium with fsr around 100-110 (no frame gen) arc raiders 60-80 1440p with fsr (no frame gen)
