why do you have the fans in a HAF 932 on high? I would expect the HAF series to provide a ton with them on medium, is it getting too hot when its on medium because i imagine its like NASA's wind tunnel in your case with everything up to high.

230mm's will be a bit trickier to find as the HAF 922 and 932 are the only cases i know that use them. SilentPCReview has some fan roundups from a few years ago but i havent been able to find a good up to date one of 120mm fans.
