I think it would physically fit, but PhysX cards require an auxiliary power connector (a 4 pin molex connector like those used on desktop PC drives), so it wouldn't work in a D\Dock without some serious modding . You'd have to first relocate the power connector because there is no clearance behind the card, then you'd have to figure out a way to supply power (and enough of it) to the connector to drive the card. Then after that, there is a good chance that you'll have cooling issues because the card will have no clearance around it for air flow.
