If you had a case without the massive mesh area on the side, you could probably have done with half the fans. You don't need a fuckton of fans if you just design for proper airflow. Like, you won't get any airflow across the hard drive with that mesh, because the exhaust fans will just pull air in through there, rather than pulling it in the front and across the drive. The fan on the side is fine to pull in some extra air and push it across the mobo, but the mesh just short-circuits the whole thing.
