Project complete!

I repurposed an old Thinkcentre m93p mini PC into a gaming console thanks to #bazzite #linux
I upgraded it with a brand new SSD, 16GB DDR3 RAM and a Wi-Fi/BT chip. It's too old for Steam Gaming Mode, so I configured auto-login and Steam Big Picture Mode for a controller-friendly, click-free boot.

Most importantly, I had to add
PROTON_USE_WINED3D=1 %command%
as a launch option to most Steam games to force OpenGL over Vulkan. My partner uses is as a Stardew Valley machine :)
