You can, but you'll be limited to USB drives for expansion after the internal drive is full.
Do you know if your current media requires transcoding?
I'm running my server off the Synology NAS, but this is really the most expensive way to run JUST jellyfin.
I would recommend picking up from Dell outlet or similar a desktop that has spacw for additional drives so you can put some larger drives for all your media needs.
Judgment Rites
Starfleet Academy: PC
--with lost missions expansion
Star Trek 25th anniversary (Gameboy and NES versions)
Star Trek Armada
Less popular games:
Star Trek Starship Creator
Star Trek deep space nine the fallen
A few Star Trek games on the c64, but I don't remember the names as my brothers would load those up. Lol
I set my server to power cycle each day and be off for a few hours to prevent my self from any issues with the mono runtime that jellyfin is using.
I wonder if .net is on the roadmap....
