I attest to this thing being LARGE, ive used all mid towers prior to this one. Lotta room to work inside this case. I have a 9800GTX+ and a cooler master V8 on my cpu (big heatsink) the V8 barely fits, but its a really big cpu cooler, 9800GTX+ fit with plenty of room to spare. All that space makes for great airflow and fans go in every nook and cranny in this thing. Excellent cable management as well. Also, it looks cool as hell.
Cons: you can see light bleeding out from all the corners of it (i.e. theres alot of space where different parts of the case connect.) case doors fit loosely, dont get me wrong, they are solid and wont fall off or anything, but they will rattle a bit when you carry it.
The above cons wouldnt change my case decision if I had it to do over, as it doesn't really affect anything, ones cosmetic and one is noise when you carry it.
