I kinda started a “seedbox” for at least my niche torrents. Most of the mainstream things I download I don’t normally leave to seed that long as there’s already plenty seeding, but a lot of the documentaries or other things that only have single or double digits seeding I’ll make a copy and leave it to seed for a while. I used to host my Plex server from that PC and when I build my new dedicated server I left the storage intact, but transferred my whole library over, so I have a large amount of unused space doing nothing else.

I’m also fairly new to all this. I’m now using Jellyfin for selfhosting. What’s the benefit of enencoding everything?

Same. Haven’t had any problems.
