I bought this case to replace Antec 900, but after 2 months I've switched back !
With four (4!, bottom, top, side, on gpu) extra 120mm @ 800rpm fans + the 3x 140mm I belived SLI GTX260s would get cooler, but I got terribly mistaken.
I took off the whole HDD cage for better airflow from 140mm intake, leaving me only one HDD slot.
Temps got up to ~48C idle and in Metro 2033 about 70C, this is with gpu fans @ 95-100%.
Switched back to Antec 900 (had it painted black inside, looks really good) and with the original 3x 120mm + 1x200mm, all @ low, I have <45C idle, load is probably 7C lower.
note that I had a 120mm blowing from the side door + another 120mm resting on the lower gpu, blowing on both cards with CM 690 II Adv !
The advantages I get with Antec 900: My only HDD is positioned at bottom of case, both 120mm front fans have NO resistance, blowing directly at gpus.
so...my new CM 690 II Adv is in kitchen w/o any hardware installed.
Good with it was: Great cable management !
Make a hole!
