Using a 360 PUS to power a PC?

[Pug]

Posted this in general hardware, but the subtleties were lost

I've read lots about using a PC ATX PSU to power a 360, but nothing on doing the opposite: converting a 360PSU to 20/24pin ATX.

Doing so would give us 205Watts of external silent power - perfect for a half decent ITX gaming sytstem.

Any thoughts/ideas?
