Beyond some cables, the build includes a TFT screen, a small handmade case, a keyboard and a mouse, as well as the Raspberry Pi itself. You can purchase the case if you're interested, but it seems easy enough to build on your own if you have access to a laser cutter (your local hackerspace has one, certainly). The end result is a pretty cheap little portable system that's easy to put together. Head over to Instructables for the full guide.
