Those are dependent on the relevant torrent being available and seeded
Jellyfin/Plex and Radarr/Sonarr + Usenet, you’ll have said file once downloaded for as long as you want, but requires considerably more storage space and torrents suck for older, more obscure stuff. Usenet doesn’t depend on seeders, and the big boys have something like 15+ years retention and you’ll always download them at full speed (no tons of seeders but slow upload speeds to worry about either)
I store my entire Plex library on an old Dell t420 server which has an old spinning disk raid array and it performs well enough. And if you’re able to direct play the files they you don’t even need a strong CPU when hosting Plex, you can run it on a raspberry pi.

So it’s a matter of personal preference
Can the storage be regular ol slow ass HDDs? That sounds pretty sweet honestly
