Liquid Nitrogen Cooling at Home?

newell98 asks: "Given the rise in popularity of water cooling systems for home computers, I was wondering how many slashdotters have played with the idea of cooling their system with liquid nitrogen? Lots of super-comps use them (or used to at least), and I'm curious about who's played with the idea of taking home computing to the same level?" The thing to remember about Liquid Nitrogen is that this stuff is generally not safe for home use. It must be stored and used with care or serious injury can result. I think this is why not-too-many people use such in overclocking. Water is by far more easier to obtain and is harmless to boot. Now, after saying all that, have any of you tried using liquid nitrogen in cooling a home or garage-built computer rig? What kind of safety precautions did you take, and how well did your cooling system work?

I'm sorry I never took a picture of the Cray 2 that was upstairs. There was a very pretty fountain designed to give a visual indication that the coolent was in fact circulating.

If you were lucky, you could see a little bubble rise off the circuit boards.

Of course, the Connection Machine over next to the Cyber was more flashy, with 64K little red LED's flashing all the time...

Why, yes. I am a rocket scientist.
