Which Video card can I get to WC?

I am getting a Maze4 GPU waterblock. I have an asus x600 XT PCI-Express video card, which I plan on removing. I plan on buying an x800 XT PCI-Express video card. Thing is, I'm not sure which will work, I looked at HIS and asus cards and i think the fans just comes off with screws or pins. Anyone water cool a PCI-Express video card? Any recommendations of which x800 XT PCI-Express card I should get, that can be water cooled? Thanks.

hmm, i think most all Xx00 cards have the same mounting holes...not sure tho

yup the maze 4 works with the x800
