About once a year I disconnect the box, take the cover off, take it on the porch, and approach it - very slowly.

This has a Radeon 3200 graphics processor built in. I was able to play some pretty stout games on this GPU (at low levels) on my kids computer. It should be able to do home theater if you ever decide to go that route.
