This Xbox looks like it's straight from the set of the nonexistent Fallout movie. Post-apocalyptic scratches, dings, and peeled paint make you feel like this Xbox 360 has seen more than just the inside of your home theatre cabinet. Too bad you can only swap out the faceplate on Xbox 360s, or someone could make a killing manufacturing these for the public.
There are already plenty of full-case mods, they just aren't supported by MSFT, and installing them can presumably void your warranty. That said, there are quite a few guides out there for installing a full case mod, and it doesn't look all that difficult.
decalgirl.com has some full case mods (I think) and a ton of full case skins (I know).
