Haha sounds awesome. How much did it cost? Another thing you could consider with that much flow rate is a distribution block. Think of a waterblock that gets feed from the pump and then has 3 outlets... a 1/2" one for the CPU, a 3/8" one for the VC, and a 3/8" one for the NB. Then they all return to another distribution block, go through a radiator, and back to the pump. Just a fun thing to consider
