Thanks for asking, OP. I'm in a similar boat, except I don't even have a computer to get started with yet, only an old phone if I wanted to use that (not trying to do things on my daily). Thinking of buying a raspberry pi and diving in but dunno where to start.
Have plex and someone kind enough to share their library with me, but it doesn't have everything I want. Could be worse tho, I suppose.
I'll keep an eye on this. I use discord exclusively for gaming purposes, and voice chat is pretty important for that bc I'm still on console mostly for the next year or so (building a pc finally, thanks to a new job). So if they can get that going, I could convince several people to switch once I'm also on PC. Till then discord for my PS5 is about the best I can hope for.
