I waited months for Google to release a firmware patch to unlock Bluetooth. Eventually, I got tired of 4 mostly bricked (could still use them wired) controllers laying around and tossed 3 of them. I wish I would have kept them all now, Stadia controllers are some of the best, I may have to pick up another one online.
A mini PC is the way to go if you want to self host a media server such as Jellyfin. You have to do a little research, but you can find mini PCs with Intel chips that have Quick Sync for transcoding for around $100 on Amazon.
