I made the mistake of doing that to my old case. Very very sharp edges after I cut, and I ended up slicing my hand really bad each time I reaced back there. DOH! You think I would have learned my lesson after the first slashing.
It's not the rear fans that bug me, its the front. They are closest to me, and thats the fan noise I hear the most.
PS: Anyone with a chieftec- do you guys notice a problem when it comes to cleaning the dust on the front grill? My mom mentioned that "Thats a problem with you guys- you never think about how hard cleaning will be before you buy it".
I guess she does have a point... has anyone had a hell of a time trying to clean the dust from that grill?
