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

[Argus]

My A4000D power supply is kaput.  Does anybody know where to buy or how to make a desktop A4000 p/s unit for a reasonable price?  I've seen some ATX to A4000 m/b connector adaptors on eBay before.  Is there an ATX power supply that will fit in the A4000 desktop?  I don't want to tower my machine (like to keep her vintage) but from what I've seen, new Amiga power supplies cost more that I bought the machine for.  Thanks in advance.

I'm not advocating opening up the p/s case, I want to do a complete swap, box for box.  The problem is, the ATX p/s to 4000 m/b adaptors I've seen are probably meant for tower conversions.  I'm assuming this of course.  I was just thinking some pc desktop power supplies rated at between 150 and 200 watts might be just small/narrow enough to fit in the small space provided in the A4000 desktop case for the power supply.  Perhaps someone has done such a mod when the original C= p/s gave up the ghost?

That's what I thought.  The extra space could be taken up with some plastic or metal.  Another reason for wanting to do such a mod of course would be to get better circulation from a stronger ATX fan, possibly more wattage (the stock 4000 p/s is only 150 watt), and make the machine much quieter (my old p/s made the Amiga sound like a kitchen mixer, I mean it was deafening after a while).

Do you have anymore of those adaptors f/s?  Or where to get the parts to make one?
