ATX Raspi

I knew the Raspberry Pi was going to be a winner as soon as I saw the original specification, but I had no idea it would be this popular or that it would stimulate such a healthy crop of third party add-ons.
The latest one I found was this really clever little power supply controller that allows the Pi to shut itself down and disconnect its own power supply.
The power supply is reconnected to the ATX board, which is in turn connected to the Pi through GPIO pins.
What makes this so special is that the ATX has a PIC processor, which monitors the Pi while it is shutting down and only turns the power off, via its on board relay, when the Pi is completely ready.
