Since the main part of the PSU is on the Mainboard, a simple adpater
won't do the trick.
At least the voltage regulators would have to be removed.
The output lines of the the ATX PSU then would have to be connected
where the output pins of the voltage regulators were removed.
This all can be done by soldering an drilling (the voltage regulators
are mounted with rivets).
But there is another problem: Not all ATX PSUs deliver -5V.
According to wikipedia, the -5V supply was dropped out of the ATX specs
in 2005.
