Can you put a soundcard into the bottom PCI-E slot? Im putting 2 GTX280's in the 1st and 2nd one's (they will be right next to eachother) so i want to put a X-FI Titanium PCI-E soundcard in that last slot.

I cant put the 2nd GTX280 into that last PCI-E slot cause my PSU is on the bottom, card doesnt fit at all.. not even close

So can i put a X-FI into that slot?
