I've had the 900 for 4 years, from before when I had only 1 card (8800GT) and 1 HDD. Things have changed a lot since then, and since I like it a lot anyway, I thought I'd save a little cash on the case since I'm spending so much elsewhere
It has a hole on the side for an intake. I can't find any fan that will fit that works worth a crap as the 120x25mm fans that typically are used for the side fan are too thick. My ginormous heatsink prevents me from using a normal fan. I can use half-height fans but the few that I found really sucked and weren't worth it.
The only area that needs more airflow is the top GPU (as you can see from the picture my sound card is suffocating it.) However I bet a side fan would help that a lot.
Your post got me thinking. I found a fan that might be worthwhile ( http://www.amazon.co...m/dp/B002CYPWTG
) that's half-height. Hell for ten bucks think I'll try it out. That top GPU could use a little more air.
