Setting up first WC system and need help on gpu block. Here's the set up ,Storm cpu block,D5 pump,BIXII rad(4fans push-pull). Currently have 6800gt,looked at the DD6800 block but, it seems to me there could be a fit problem with covering mem and gpu. to fit properly they would have to be on the exact same plane and it would restrict me to using it only on a 6800. In the future I plan on going SLI either with a second 6800gt or (2) 7800gt's so after much searching it seems the best would be something like a DDactel low profile Maze 4 block which I can use with either gfx. Is this the best way and would the Maze4 be what you would recommend, or is there another block which would work better in my setup. Thanks for any help.
