Sure. If you are comfortable with computers, this should be a breeze. I currently use Docker as my server platform, which can run on top of any OS you want, but I run it on debian. I run a Gluetun container + Mullvad for VPN, qBittorrent as the torrent client, Jellyfin for media, Jellyseerr for user requests, Sonarr for TV management, Radarr for movie management, and Prowlarr for torrent indexers. All of these run on separate docker containers. There’s some trickiness for getting all the sketchy traffic going through the VPN, but there are plenty of guides out there, and in DMs I’m willing to offer support, albiet pretty slowly. If you have used Plex in the past, you can replace Jellyfin + Jellyseerr with Plex + Overseerr and the rest of the system can stay the same (although plex has been making some weird moves lately, and isn’t free or open source, so I’d stick with Jellyfin if you can get past a relatively ugly UI).

The nice thing about this setup is it’s pretty easy to expand to music, ebooks, and audiobooks as well, but for those media types there is less automation for user requests. I haven’t had any issues with scaling up either, I’ve currently got 150+ TB of media.
