Long story short, I had my Plex media server running on my gaming PC. I don't want to do that anymore. I tried using an older laptop I have but it sometimes struggles with 1080p content and buffering issues. I looked into a NAS plex server but I'm finding that if I want one that can actually play 1080p/4K content (future proofing), it's going to cost me a lot of money.
I know another option is building a PC and going that route. I'd like to think I know enough about building a gaming PC but really have no idea what to look for regarding media server hardware. I'd like to keep it around $600 if possible, is that being unrealistic?
If I could stash the PC in a closet or somewhere out of the way and just remote connect into it for Sonarr and whatever other apps I want to install, that would be perfect. I tried reading up on the Internet but there's so much information it's making my head spin.
