Hi. Does anyone know if the placement of the GPU on video cards is standard? Reason I ask is, I'm looking at getting a Zalman ZM80C-HP heat pipe cooler for my GF4 Ti4400, but in order to use it in my XPC I'll have to cut out a window for it to stick out. If I decide to say upgrade to a 9800 Pro AIW a few months down the road, I'm wondering if my hole will still be aligned with the Zalman unit when I switch it to the newer card. Thanks.
