My Antec Aria cube case is a bitch to work with, I need to remove all my drives just to change the cell battery. That open skeleton case makes any changes or maintenance a breeze. Antec just came out with a smaller version, but it doesn't support full height cards.
Some will argue that it will pick up more dust, but then so will any case with fans sucking air.
