Here is a quote I pasted from EVGA website.
This card features a preinstalled EVGA Hydro Copper water block that accommodates both 1/2" and 3/8" water cooling loops. Upon first glance you will notice this is no ordinary water block, this is a full cover- end to end block, with an integrated glowing window that displays the water flow and a glowing EVGA logo on the side keep it looking slick. Also, a preinstalled EVGA backplate keep the card sturdy! The innovation does not stop at stability an appearance however; the base plate is made of chrome plated electrolytic C110 copper, and the 0.6mm thin pin matrix provides optimal thermal transfer to ensure the lowest temperatures possible
I'm not up on lc systems, but it appears the Hydro does have a built in waterblock and only lines to it are needed.. Now how DS would charge for this with the gpu's already having the waterblock installed I can't say. Call DS and they would be happy to tell ya or maybe someone that knows can chime in.
