Best build solely for streaming?

I'm new to building computers and I have only ever gamed on console. I don't want to build a powerful gaming machine. I really only want something that will be able to capture video from my Xbox at 720p and stream it on Twitch. What would be the best gpu, cpu, etc for that? Again, not trying to play any games on it so if performance can be sacrificed in regards to that but still handle streaming then that is what I want to do. Thank you
