For an entertainment machine, I'd suggest installing Steam and auto-launching to big picture. Very easy to navigate from a couch w/ a controller, and you can use it for nearly any media task you want. It does take some time to configure your media directories, but not having to deal w/ a mouse on a media machine is so much easier. Plus, since your base OS can be something like Debian, remoting into the machine for administration is eminintely doable.
