The only real reason for the box is looks, I think that it will look cool, sure wish I could stick some fish in there though like gmat proposed, the only problem is that the pump would turn the fish into chum and I don't think they would be happy being UV reactive chum in a bath of purple ice.
No lanning for me gmat and if I did I would probably just use a case full of tornado's and pair of Sennheiser's.
