I love this case—its one of the coolest factory designs I've seen in a while. It's got a retro/new age feel and it just looks cool. If I buy a new stock system, it may be this one. I'll at least consider buying the case.
They have a number of different colors and features you can add on to the case. You can even change the color of the lights in the air cooling (they lights are in the black groove pieces on the side—this picture doesn't show the lights on.) Check out Alienware's site for more info.
