When I was building the PC I referred to it as my mistress, with my Mac being my wife. So much for that.

The one I'm using right now is, that's for sure... but the new one is going to use an Antec case and probably a 64-bit processor; might not be as nice as a G5 but it sure isn't ugly. Antec makes some nice stuff.
EDIT: Here are some pictures...

I got that green... thing... for free. Hence the nice quality replacement.
