Very nice projects but just a few things though:

-The reservoirs don't seem to line up vertically and are not on level with each other.

-The way the tubing comes of the lower videocardblock is a bit awkward, i'd cut the rectangular hole in the divider plate a bit larger and just let the tubing come of the dowside of the block.

-Ditch the coolsleeves, they're horrible.

Otherwise, one awesome looking rig.
