I got the same story from an IBM marketing rep when I wanted to take an (original) US-use
PC to India to run on 220v 50Hz. He was right, but for a reason that I hadn't
considered.
In the old 60w PC power supplies, the fan is AC-operated and is specific to the line
voltage stamped on the nameplate. I simply replaced the fan with a DC-operated one (maybe
it taxed the meager +12 supply a bit, but hey, it worked) and bundled the unit off to
Bangalore where it put in several years of service.
I don't know if the same situation obtains for you, but you could also just keep the
box and substitute the innards from a generic PC power supply.
I was looking through the stuff in my garage and noted that I still have a carton of old
PS/2 Diskette Adapter/A (5.25") boxes. These were surplused by IBM and the drives
themselves scavenged for resale, but I've still got the cases complete with power
supply and cable and hardware (including the tamper-proof Torx screws) in their original
shipping boxes. They're really very well constructed units.
Anyone interested?
