Maybe instead of buying a cheap kit, I'll buy some higher quality parts from dangerden. I want to use thin tubing to cool the liquid up faster, there isn't much time before the water goes back out again to the cpu or videocard. But then again, if its too thin it will warm up faster than a thicker tube. Reinforcing the box wont be that hard. I have a strap machine in the basement used for very heavy boxes (70+lbs), the strap is high quality and should ease the friction of the walls of the container. And the container must be a type of metal. I have a thick aluminum box with a lid. The straps should keep the lid on tight enough and the silicone should hold in place.... I hope
Keeping everything in the freezer should have the dry ice last for at least a month. before any evaporation starts to happen.
