Glad you like anks build .. i love it too.. in-fact im downright jealous. lol
i had recently made a post on watercooling , so excuse me for copy-pasting
For water cooling i would say get the new Swiftech MCR320-DRIVE REV2 Triple 120mm Radiator w/ Integrated Pump along with a Cpu waterblock , some pipe and compression fittings of your choice.
Id highly recommend the Swiftech Apogee XT cpu water block.
The best tubing right now in terms of no plasticizer leech and bend radius along with a wide choice of colors is from Primochill. The Primochill LRT Tubes with 3/8th inch ID ( internal Diameter) and 5/8th inch OD ( Outer Diameter) are the ones to get.
As for fittings , those will depend on the case as well as the water cooling parts you choose.
Expect to spend close to 25k for a very good water cooling system including shipping and duty
Here are a few links.
