His solution, which I have also used, was to duplicate the lower tension cams in the mod kits by filing down the face of the cam by about 1mm. You smoothly follow the curve of the cam, but file away most of the thickness of the edge that runs around the cam face.

This makes a noticeable reduction in the dishing of the board, but doesn't seem to have any adverse effect on the seating of the heatsink or on heat transfer.

I'm currently using a GA8IPE1000 + 2.8G 800FSB, it's been fine, has SATA but not RAID.
Platypus, have you got pics showing exactly what you mean?
