Build your own computer?

[Dina Lerret]

Out of curiosity, has anyone here tried to build their own computer? 
Y'know, get case, motherboard, memory, etc, jam it all in the case,
cross your fingers, and hope it works. ;-)  Okay, maybe not that
random. {g}

I'd like to build my own computer as a learning experience (probably
to never try it again ;-)) at a later date and I'm curious if others
here have done so.

Yes, some could suggest 'just buy a Mac' but those puppies are
pricey... Then again, not buying something prebuilt [from Taiwan] will
probably be pricey too.
