Help Building a Stream Box

So I don't know if this is the proper community to post this in but after the recent shenanigans that Roku has pulled I want to redo my entertainment setup and stream my media through a box I control. I have a couple of Odroid N2+ laying around and I'm trying to build a stream box out of them. First I tried CoreElec but Jellyfin didn't work out to well for me. Now I'm trying Android but some apps (cough* Curiosity Stream) are terrible.

My question is what does the community use to stream their media? What I'm looking for is the ability to connect to Jellyfin servers, Nebula/Curiosity Stream/HiDive subscription service access, adblocked Youtube. Does anyone have a similar setup?
