Wow, just when I thought -200 was cold, check out this:

This freezer is DRY process, which turns the ice-cold Liquid Nitrogen into a gas inside the freezer, at a claimed temperature of -300!

Now, correct me if I am wrong, but if you could dry cool everything in your case, save the hard drive (which would be destroyed) then shouldn't you be able to get to, like, amazing overclocking speeds?

Should we take up a collection and try to buy one of these puppies, so the overclocking wizards can build a CPU inside it?
