If you have $850 you really, truly don't need, get this case

[Lemur]

Brilliant design if power consumption is irrelevant to the user.

Hmm, I can think of a lot of reasons to ding this design (850 of them, in fact) but power consumption didn't spring to mind. I don't see how this case is significantly more power-hungry than a standard ATX. Maybe you could explain a little?
