And if you were to go the dry ice route, since AFAIK dry ice isnt conductive, why don't they just build the entire computer into an icebox (not the hard drive), and put a regular passive heat sink on the processor rather than construct that monstrosity of plumbing. I would think the overclocked memory and chipset would benefit equally as well. Oh and of course throw in some sacks of silica gel in there, don't want to have condensation now.:]

Imagine sleeping through your computer's feeding time to find your GPU in a puddle at the bottom of the case.

Overclocking is about pulling fun little tricks to make your box do stuff that it wasn't intended to do. Usually, it's also a way to tweak a little more performance out of a non-production, home gaming system without spending money on a CPU or video card upgrade.
The point of the dry ice project is that it's simple and it gets the job done on the cheap. You COULD spend a shitload of money on one of those Vap

Re:What's next? (Score:2)
Yes. But superconductivity is necessary to maintain the high currents required to generate these strong magnetic fields. So it's something of a delicate balance with a violent failure mode. Push the magnet too hard, too much current or magnetic flux (or not enough cryogen), and it'll quench. (This is the OTHER reason why you don't want to bring metal objects into an NMR setting...)

Yes, there are materials that, when cooled, demonstrate superconductivity.
Yes, it's possible to use this property to design electronic equipment that performs better than traditional semiconductors do. Yes, many of the materials in your computer might become superconductive if cooled sufficiently.

Use two in the second layer.
Use 4 in the third layer.
On top of that place a large heatsink and massave fan or a watter cooling system hooked up to a large heatsink and fan.
As long as you use thermoelectric rated for the operating temperature each layer is going to sit at you can stack them like this and get to vary low operating temperatures.
PS: It would be more effecent to use the inner loop of an AC unit instead of a few layers of thermoelectric cell's.

Also the heat dissipation on the Pentium 4 Prescotts IS a lot even when not running overclocked. I have a 3.2GHz Prescott and it is the first computer I've ever had where the exhaust is actually feels hot.
Higher speed Prescotts had problems with the retail heat sinks - they would overheat and drop down in speed.

Use A Solvent (Score:3, Insightful)
An even better setup would be to setup a water-cooling-like system, with dry ice in a container filled with solvent above the system. The solvent would be fed into a heat exchanger on top of the CPU/GPU. No pump would be necessary, because, as the solvent in the heat exchanger heats up, it'll float up to the top, where it'll be cooled down again by the dry ice.
In any case, the costs of such a system would probably outweigh any benefit of using it.
Re:Use A Solvent (Score:2)
Better put, use of a pump will reduce the temperature difference required between the cold end and the hot end, which reduces energy/dry ice requirements.

Yup, really amazingly simple.
Just take your anhydrous CO2 tank, connect it to a dry ice mold (almost like a rigid fine-meshed cheesecloth box, you could probably hack one together if you don't already have one), and let 'er rip until the mold fills.
You can even still use the waste CO2 (a lot) for something else, with a careful setup - Just make sure the pressure drop occurs in the mold rather than at some point down-stream.
