OctoPi - Turn power supply on/off?

I recently got a Raspberry Pi B+ and set it up as an octopi print server.
However, one thing I'd love to see is a way to switch the ATX power supply on and off from it (it's getting powered by the 5V Standby line).
Is there any means to do that?
Running a Melzi board with Marlin.

do you want the pi to use its i/o to turn on and off supply as needed, or to send a code to reprap controller and have it turn on and off atx supply. also where is the menzi board receiving power from?

depending on approach, you could use one of menzi's available port pins, such as in the header, or use wiringPi language and a port pin on the Pi. I'm not that familiar with Pi modules.

Take a look at this post from Nophead (scroll down about half way) - [hydraraptor.blogspot.co.uk]

It covers exactly what you're looking for.

Derp.. I'm an idiot. I actually had nopheads' entry bookmarked for this very purpose, and then forgot about it.
Thanks.

Edit: Just set it up and it works just fine.
