Nice water cooling apparatus. Just get a pump and connect all those in parallel to a small radiator and attach it to something like the power supply. Excellent cooling. I don't know how much heat GPUs and ram put out but is it worth it to watercool it? Seems like more of a hassal unless you've got money and case space to spare.
OR a peltier. Hehe, you'd get insane temps with a 220W pelt. I wonder if it would do damage with such a high power. I doubt even Geforce 4s put out more than 12W. The only problem is the space limitation caused by PCI slots. That's why 1U coolers and H2O is nice. I wonder if socket based GPUs and external ram cartridges like we have for CPUs and their memory will be a possibility someday.
Actually that was just a project. It's not my main PC.
I use it wherever I go, in my car, and it was much cheaper to build than if I had bought a laptop, and I can also play games on it since it has a GF2MX onboard that I can overclock. It's a pretty sweet system actually.
And I've modified it a lot since the pics were taken. The monitor cable is now an attachment through the side of the top of the case. And I repositioned the monitor to center it better. Those pics are pretty bad and were taken in a totally dark room but with an excellent camera. My Canon G2.
