It may not be a true case mod but it sure is a mod of some sort! It uses a transmission cooler from summit racing (that is basically 2 10" X 10" radaitors welded togather on top of eachother), 2 120mm antec fans, a hydor 300gph water pump, a Spire fan controller, custom reservoir(PVC and Lexan), and an 80mm fan to cool the inside of the case(pump gets a bit warm). The system itself uses 1/2" ID lines and splits into 2 3/8" ID lines after the manifold on the side of the case, the manifold is set up so that the cooler can be detatched without draining the system. The CPU is cooled by a Danger Den TDX cooler and the GPU is cooled by a Maze 4 cooler. The temp on the CPU never varies more than 6*C and the GPU temp never varies more than 8*C. Everythng from the radaitor shroud to the case on the bottom was made from scratch and is all alumnium sheet and plate. I took care to make sure that the only metal that the water would come into contact with was copper and that allows me to run the system without any additives. The computer case is lackluster at best but it was turnig into a money hole :( oh well that will be my nex project.
