I was looking at that one and heard about a slight flaw in it's design, that you need 2 slots to mount it and you really can't mount it with anything above it, like in the top 2 slots, otherwise you can't get at the reservoir.
Trax.... 4 screws it slides out like butter. 30 seconds. I run antec 900 case. My gtx280 is so big I had to let cooler stick out a tad but it runs even cooler since it draws some outside air!
