FYI...for anyone having issues with SATA connectors and over-sized video cards, the answer to your problems can be found here...low profile connectors
I was having problems with my eVGA 640MB GTS ACS3 not seating correctly, these cables are low enough for my video card to clear the connectors.
Thanks for that link, Armyoffoo! Out of curiosity which part did you end up buying and using in your setup?
