Home entertainment with NAS?

Hi! My goal: I want to set up a beamer projector in my flat and connect that to some kind of 'always on' machine with which I can stream (currently Netflix a bit but that really is not a priority as I am thinking of cancelling it) but would also like it to be a torrent client (I have a VPN) to download some media. Though something like popcorn time would also be nice, though that's also something that I would only use behind a vpn for obvious reasons.

I have a pi5 or and some older NUCs hanging around that run well with Ubuntu. I know that something like kodi does not play nice with Netflix (iirc because of drm).

Should I use the pi? Or better an Ubuntu and do the power management best I can myself?

What would you guys say is a good way to try this out?

Edit: TIL I thought beamer is a word that German borrows from English, so I assumed it's the same. Nope, in German 'beamer' has very weird roots (https://de.m.wikipedia.org/wiki/Videoprojektor) so Germany stole an English word 'beam' but it meant project... Weird
