Honestly I’ve got the kids bedroom tv on a Pi 3 running LibrElec just fine. Kodi isn’t that resource intensive so it works great. But if you’re feeling fancy setting up a db to hold all your info so you can share it on multiple end really is nice. I love being able to stop a movie in the living room because I’m getting tired and pick it up in the bedroom at the exact same spot.

If you ever want to buy raspberry pi, don’t forget to get a cooler either passive or active. Those things gets hot quickly without a cooler.
