I've come into a 2018 Intel Mac Mini, its got an i7 and I've upgraded it to 32gb of RAM. I feel pretty constrained on MacOS as I mostly just game. How function are eGPUs under Linux? I'm pretty comfortable on Linux, its what I use on desktop daily. But I've never tried anything with external graphics on it. Xorg seems like it could be a mess with config files, is Wayland any better?
I’ve got one running in a Proxmox cluster. Getting it setup was a bit particular (due to the T2 chip if I remember correctly), but it’s be working flawlessly. I use the quick sync feature of the iGPU for my jellyfin container.
If you were going to buy something new, I think there are more cost effective boxes of about the same size and spec, but if you’ve got it already, you should definitely start playing with it.
