If you want a wild looking yet sturdy case, go NZXT. Personally, I like more subtle cases, not as far as a sleeper case, but still subtle. Personally I don't think cases should have so much plastic on them.
Nonsense, without Windows i'd have no excuse to clean up my wires and without lights i'd have no excuse to have a window. And without doors everyone would have to paint their Optical drives to match their non-black, non-beige cases.
