Depending on if what your solution can do I was just going to use this to turn off/on the ATX power supply. I am running the Avalon Chips off of PCI P6 and adapter to P6.
This is my exact plan. I will use this breakout board only to power the ATX power supply on essentially. However I am intrigued by what ik2013 is working on and when more details are posted I might be considering it if it's an elegant solution.
