You absolutely can. Currently running mine off of my desktop, but it’s overkill and have a few coworkers that used nucs/cheap mini PCs to setup jellyfin. Biggest thing is to make sure you have enough storage to hold all of your media, then you’re fine.

My father got and installed two of the newer nest thermostats, and they are bar none two of the most annoying tech devices I’ve ever had the misfortune of having to fix. Have literally spent hours debugging them when changing the wifi password, they don’t support wpa3, and the setup app feels like a half assed student project. I know this audience probably isn’t interested in getting one, but if one of your family members gets some for free, do NOT let them install them.
