I received the card today. This card doesn't fit in the first pci-e slot, the one closest to the cpu , it bumps into the cage that houses the cd-roms. Luckily my MB has several pci-e slots and the 2nd one is 16x also. Using the 2nd slot it fits just like Max1s described. It slightly bumps into the hdd release plastic things, which you can easily bend a bit and then it snaps into place. Although now i have a few uncovered expansion slots in the back of my case from my last video card.
