Thanks!
On the top panel, I just cut through it.. I didn't remove it or anything.
I finaly got the 92mm fans in the front too, last week. The drive bay actualy fits right around it, just had to bend the little lip straight with a pair of pliers.. I left the 80mm fans in the rear, because it was going to be a very tight fit. (I know other have put 92s in the back though)
