My company makes an ATX Starter which automatically switches on/off an external ATX PSU when your computer is powered (the ATX starter is £15).

ATX PSUs are built as cheaply as possible. I'd go with a dedicated switching supply over an ATX any day. Besides, most of the ATX power output is on the 3.3V and 5V lines, while TECs need 12-15V. So you end up massively overspeccing the PSU just to get enough 12V current.
