I have a synology NAS, two bays with 4TB in raid.
Mostly used for Plex (Netflix alternative and for music streaming) but also find these useful:
Vaultwarden (password manager) Virtual machine (for torrenting) Sonarr (torrent indexer) Radarr (torrent indexer) Synology Photos (photo backup) Synology Drive (personal cloud storage) Joplin (notebook)
Probably some other stuff as well. I highly recommend mariushosting.com if you have or end up using a synology NAS. Amazing tutorials for just about anything.
Very fun, Civ is great if you enjoy board games. Basically a board game on pc or console.
