Did you build it yet? And how did it go? I’ve just built a fractal terra jade, with a nearly completely spare parts bin spec; Vega56 (ex-classic Mac Pro) i7 2600 (ex-iMac 2011) 2x4gb ddr3 ram (also ex cMP) 1tb SDD 500watt silverstone SFX-L (toight!)
Running Linux Mint 21.3 Have installed WoW via Steam compatibility mode, and playing all my steam catalogue as trials. Borderlands 2, Pre-sequel, wolfenstein old blood, and some GOG games. It’s actually very competent at 1080p and I’m not finding I’m having to turn much settings down to enjoy good frames.
I found that all my keyboards didn’t have functional modifier keys while gaming, in wayland. Switched back to default cinnamon, and it all works fine again. Linuxmint
