TweakTown has managed to get hold of a couple of pictures and some details of an upcoming water cooled Radeon HD 2900XT card from Asus.
Asus has named its card EAH2900XT AquaTank, suitable maybe, but it's not a name that will roll off your tounge.
The card comes with a combined radiator/water tank and the pump is fitted to the card, similar to MSI's solution.
Aparently the card also has a flow control gague with a built in alarm in case something would go wrong with the pump or the tubing.
