My go-to for “server” hardware:
- Old office desktop: Dell Optiplex SFF, HP Elitedesk SFF, Lenovo Thinkcentre SFF
- CPU: 7th, 8th, or 9th gen Intel i7, preferably something with vPro (really neat OOB management - keep it local)
- RAM: At least 8GB
- OS drive: 256GB SSD at the minimum
- OS: Debian
- Media storage: Something large enough to store your media. 3.5" HDDs are great for this, but SSDs are better if you can get your hands on a large one.
I also have a NAS based out of an old HP Proliant ML110 tower server case from 2004, outfitted with some modern-ish parts. I like it quite a lot. Very server-like, it does the thing.

There are a lot of references to Firefly in Castle. It’s quite entertaining.
