If you are debating on eventually doing a media server, Arc 380 is small form factor, no external power, crushes all encoding benchmarks, and only $150. Plenty of good used card options from a few generations back like some mid-tier gpus, but pretty future-proof as far as server performance if you have kernel 6.3+
Edit for anyone later: ARC sucks ass right now for gaming on linux as intel devs are 90% windows focused. Don’t take this advice for a desktop GPU
