The random office PC with an older i7, no GPU, and two hard drives I was using idled at around 70W. So… it goes either way.

Edit: This was a “standard” ATX tower PC and reading your other comments it sounds like that isn’t what you’re referring to.

Having recently switched from baremetal Ubuntu Jellyfin to Docker, use docker. With Docker I know exactly where Jellyfin is storing my data because I tell it where. This means I can move it and spin it up from any machine the same every time. Moving my files over from Ubuntu was painful because they store it in weird locations and it’s spread across the file system, plus my media mount locations are different. This would have not been a problem on Docker.

It’s not the ‘one click’ solution some people claim, but the up front trouble is worth it for easier management, in my opinion.
