How to Cool Your PC with Dry Ice

After liquid metal and liquid nitrogen, here comes dry ice! What's next?
A computer makes it possible to do, in half an hour, tasks which were completely unnecessary to do before.
Sure, more dangerous. But probably more handy to build and could last longer. Valve set to slow dripping, pipe outlets (possibly with some spraying tips) over the radiators, possibly even electric valve with some temperature feedback loop - temperature rising, pour more, temperature dropping too much, cut off. 1 liter is something like 6 cents in bulk, so it should last quite long. Sure pouring a bucket of liquid nitrogen over a PC won't do much good, but you should be able to release it as slowly as you only desire, so...?

I don't want to buy dry ice. Isn't there a good way to make it at home?
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.
