I'm baffled. If it were for a business we wouldn't be here anyway. It is a school project, a fierce competition which is based on originality and skill. We came here to learn as we're only 17 and have little experience with this field.
I have agreed with my friend that a radiator is the way to go. Anyone have a different opinion, please speak now.
Some components eg: ram, NBs, video cards will not be watercooled. Basically, what will happen next is to arm a computer with hardware, build the blocks, and watercool. We don't have 5 pcs so we'll just watercool one and then place a heater element to simulate the load of other computers. It is basically a scaled model. We are cheap bastards after all and will not afford more than Lm150 ($400) between us 3. Most of the things will be either:
a) stolen
b) lended
c) salvaged
We would then have to buy some materials eg: copper stock. The next thing to do is determine the material of the heat exchanger that my friend found at his dad's work place. It is quite large, bigger than a truck rad.
Thanks for your replies and keep them comming. They motivate us
