I've seen this picture (below) , but im not that sure if its the reference card. Anyway, there are several mounting holes that i can see, and the current memory placement it shouldnt be that hard to watercool it, maybe one big happy block (like morph's). Im not really sure of those placement, but hey, its not "really out there", so i'll (we'll) have to wait and see.
PS : if the images dont open, please let me know.
PS 2 : it seems that Nvidia is copying the p4 cover scheme. I dont really like it.
