I had this thrown together to start with, one of Petra's kit's and once satisfied that I knew what I was doing (first W/C build) I took my rig apart and here's how she ended up. My rad and pump are in the tv stand that was used as a base for the case.

I have changed the tubing that Petra's gave me with the kit to 1/2" id, 3/4" od. Plus I guess the small tubing that came with the kit when I tried to push it on the plastic barbs for the rad, I pushed too hard and caused a leak. Or the rad was defective. Reguardless, I tried many different ways to stop the leak and finially took it to a rad shop and had it fixed. Cost as much as the rad. Maybe I could have bought the resin and solder and a torch and did it my self, but I wasn't sure I could. In the pic that's rtv all over the rad and tubing.
All in all, I think it turn out good, just need to buy more blue stuff to put in the water.
