Debian as the OS, Portainer to have a WebUI so that I can manage containers a bit more easily. Jellyfin to stream movies, Transmission-OpenVPN to download movies, Blog container and caddy to manage the traffic. Wireguard so that I can connect to my home network remotely. The server has a GTX 1050Ti so that it can transcode the movies, was a bit of a challenge to be able to successfully use the GPU in the Jellyfin container, but works flawlessly now. I plan to setup a Nextcloud or maybe Syncthing to backup my own files and photos, but I'm not sure how I want to handle backups, maybe just an external SSD. Cloud backup would be cool. A local Bitwarden server would be nice as well, but maybe I'll just switch to good old Keepass. Has a Ryzen 3, 16GB RAM, 3TB storage (2x 3TB in a mirrored RAID). What stresses me out a bit is that I don't really monitor the state of my RAID, so theoretically it could currently be broken without me knowing. I'm not doing anything against this because I currently only store movies and shows which are also copied to an external SSD for travel, so I don't really care if it goes tits up. But if I want to start hosting my files and passwords, I gotta make that more stable.
