How to make/buy a cheap non-Commodore A4000 power supply??

Hi-
  I happen to be the guy that had the ATX to A4000 m/b connector adaptors on eBay. It is possible for you to keep your Amiga "vintage" and use this adapter. What you'd need to do is remove the circuit board from the Amiga power supply and install the ATX circuit board. You may need to drill holes in Amiga power supply case to mount the ATX board, and then use the standoffs that come with the ATX board. Should work fine.

  The plug for the motherboard is made by AMP, but to order from a third party you half to buy a 100 or more. I had a few of these so I made as many as I could.
  If you would be willing to go to the trouble of cutting the one off your power supply I would make one up for you for $20.00. Let me know.
