Really nice job!

I think if you swap the tubes on the NB it would give you a better bend radius, if you are concerned about it that much. (Highest CPU barb to the lowest NB barb). The NB hold down definately looks like it will get in the way of clamping, i'm using the Danger Den 680i block because the barbs have much better locations. Do you plan on splitting one of those loops and cooling that ram or is it just for looks?
