Might actually build and sell these things with steam OS loaded on them. Would it be a good idea?
Here is the parts list: http://pcpartpicker.com/p/X6HXYJ
If you're going to do that, you should include some sort of SSD for the OS so you can market them being able to start up as fast as a console.
This is a lot better

Question, would you be able to just download the games and play them on your TV?
