I'm not sure we're talking about the same thing, but I couldn't get the hole on my twin frozr III gtx 570 to line up with the holes for the expansion slots in the back on the first pci x16 slot (by slot i mean the hole on the gpu that aligns with the threaded hole that the tool-less screw is threaded through), forcing me to move it to the next slot where it lined up only slightly better. It must a be a physical compatibility problem b/t my mobo (same as yours), the case, and the card. I RMAed my case as it came broken, but when I get everything back in the new 922 when it arrives (hopefully tomorrow), I'll post pics if i have the same problem.
But what i mean is, the tool-less clips, did not swing open fully because the rivets were blocking them from opening all of the way.
So i couldn't put a graphics card straight in, i had to put it in at an angle and feed the rest in, which is difficult.
It works perfect now, after melting away an area for the rivet.
My 932, looking at the back you can clearly see where the rivets are, slot 2 and 6 which are right behind the clips.
