Crunch time is on us, and we have just over a day to put this Monster-Mod together and test it. After mounting the radiator on top of the case with a block of high-quality, machined aluminum (see Figure 1) that we found in our scrap bin, it's time to connect the components.

It used to be the shoulder joint of a 1980s robotic experiment. You can also bolt it to the side of the case, or make it stand-alone. The only limit to design is your imagination.

Tubes and Fittings

To link the system parts, you can use any kind of half-inch hose. I prefer clear, flexible PVC tubing (see Figure 2) because it looks good. It also lets you see the water flowing. And if you add UV-reactive dye to it, it looks cool against the UV lighting in your case. I think the optimal way to attach hoses is with spiked connectors. These plastic or metal "fittings" taper at each end and have grooves to grip the tubing from inside. You don't need to use hose clamps with them, but I think clamps are a good idea for redundancy—especially if you'll be carrying your setup to LAN parties. You can also use special thread-sealing tape around the fittings to help ensure a tight seal. Half-inch fittings and accessories can be found at any case-modding store online or on eBay.
