I wonder if the "Seller" pulled it because he/she received a cease and desist letter from AMD? This prank probably resulted in the Seller being barred from ever receiving Engineering samples AND a return of the 7990 to AMD.
Fitting the videocard in a casing is the LEAST of the worries... Question is would my wallet be able to accommodate something that expensive? To come to think of it, I would probably not even use it, I would keep it locked up tight! What a waste of resources... I would rather spend the cash on a decent car and a BEAST of a rig!
