Been running a Plex server since it was a mac port of xbmc. Before that I used to mod Og Xbox’s. Happy to help out here!
I'd love to help if you're still looking, have run Plex for 5 years, started off on a pi, and am now running in unraid in a docket container without about 20 other containers supporting it.
I also maintain a fork of invitarr with jellyfin support and some updated discord features.
