It's an attractive case, though I'm waiting to see what prices will be like.
That said, since it's drawing air up from the bottom of the case, why not slap a truly massive fan on the top, why the relatively dinky little 120mm on the back? I can understand it as an optional mounting point, but that case looks like you could easily get a 200mm fan in the top, maybe even up to four 120mm fans if you want to go completely overboard.
Can't really tell from the available pictures if you could do this, but considering the design it seems like a wasted opportunity. I've been heavily favouring top mounted exhaust fans on recent builds, and found them very effective if you can keep them clean.
