Cryogenic Mouse Mod

that one is pretty cool.
Not exactly correct. The metal cases are there to diminish any interference your computer might cause to other electronic devices AND to reduce the interference other electronic devices might cause to your computer! They cannot totally shield your computer but definetly do a better job than not having anything.
Suppose, for instance, that you have an poorly shielded switching power supply. These are not terribly uncommon among cheap computer equipment. Generally it would be a brick that's between your electrical equipment and the outlet. Now take this brick next to a regular monitor (pretty poor shielding here too) and you begin to see nice interference effects! Now guess what happens if you have something similiar next to your unshielded computer.
You don't even need to consider anything related to memory but just the hard drive cables at udma speeds of 33 and over are highly suspectible to noise! It won't take very long until your computer is pretty much locked up and you got corrupted data on your hard drives. I've even had problems from using bad udma-cables (all the problems disappeared when I just got new cables) due to electrical noise probably generated by the fans or other hard drives or the powersupply.. who knows.
The fact is that solar radiation isn't going to do much to your computer (satellites are affected, however) unless you live in polar area and the flares leake from Van Allen belts, but that's a different story. Not shielding your computer is a bad thing because of not only the interference it creates but also the interference it receives..
