Yeah Voodoo cases are wicked cool but a decent spec'd voodoo would cost a lot more than an AW.
Also that dell case is like 3 years old and has been replaced....they aren't AS ugly now.
That Dell case is my current desktop. Yes, it's fugly but I just threw that in there to show you just how manufacturers don't care about case design. While Dell's have gotten a bit better, I still don't think that they are as nice as the P2.
