This is veering into offtopic-but-related territory, hence the subject

I am interested in knowing if anyone here would like to collaborate on  
an open source, build-it-yourself "80 Plus Gold" (see http://en.wikipedia.org/wiki/80_PLUS#Efficiency_level_certifications 
  ) power supply PCB design. I'm no longer a noisebridge member, as I  
live in the Mountain View area, but collaborating on-line and in- 
person occasionally would work fine. Given that the price of even the  
cheapest 500+ watt 80 Plus-certified PSU hovers around $100 USD, I  
think there'd be an interesting following of folks who have bad PSUs  
and don't want to shell out that kind of cash for a replacement. Since  
many semiconductor manufacturers provide reference PCB designs for  
their 80Plus ATX PSU components (NXP, nee Philips, is one which comes  
to mind, that I've found, but I'm sure there are others)
