Heh- was just about to go look there, but you were faster than me.
Last time I saw this I had a poke round the net to try to find out the real story- couldn't find anything definite, but I concluded that it could have come from SA cos I think the voltage on the PC is correct, but the snake looked wrong for what the mail says it is - I think I decided it looked more like some kind of grass snake, but I know nothing about snake identification so I could be utterly wrong.
Still not what you expect to be poking out of a PSU though..
