I setup jellyfin plus the arr stack on an rpi4 and man has that little thing changed my life, all the content I could ever want just for the cost of a Usenet provider. Hope you enjoy man!
How’s the rpi4 as a media server? I wanted to do that too, but i looked into it when the 3B was new and the general consensus was that it wasn’t really ideal.
As an aside, raspberry pi’s are so cool. My rpi3b running retropie/ emulation station turned out so great, and it runs way more games than I expected.
