What I had wanted to do when I was fist planing the system, was put all the water cooling into my old shuttle SN41G2. But sadly due to drive lents, I would not be able to fit the VGA cooler for the 9800pro in. So I scraped that idea and went and got a Thermaltake Skull from stock in Elara. I went with the skull as it came with a side panel and is quite a sturdy case. So cutting into it would not cause any problems with it.
Heres some pics..

Not much was done to the frunt of it, that you can see. The temp and fan control unit is about 2mm out more than when the case is not moded (its a really big Rad for the water cooling) The "Thermaltake" sign on the front is meant to light up. But I removed the controler as it looks crap! I'll be changing it with something better, once I can think of something to put in there

I had to cut a rather large cut in the case for the fans to have airflow. The Rad is below the fans and goes from the PSU to the frunt of the case. There is about 2mm on each side of the drive mountings for clearance. I put Antec Nice killers on the PSU and two 120mm fans. They keep the vibrations down.

On the side, I removed a "bracing bar" that runs accross the middle of the case. (its used for making sure cards dont pop out of there slot and to hold an extra HDD and one fan) Installed 2 UV cold cathode lights. One running accross the bottem and one on the bottem side as seen.

If your wondering about the winding path of the tubing going from the Rad to the water tank and the pump to the CPU/Chipset/9800pro. I found that when I turn the PC off, a small amount of air that is in the tank, Comes back up the pipe and was going into the Rad and casing an air lock. This bend going down stops this from happening.
