when you are trying to revive an IBM 5150, that :

keyboards - at least 50% of your MFM drives have passed away in their
sleep. - you don't remember which is the last DOS version that runs on
a standard 5150
Aside from the -5 line (which can be gotten with a 7905 voltage
regulator off the -12 (and may not be needed for anything but the
original 16-64K 5150), most ATX supplies can be pressed into service
for AT use, mostly by changing the connector and manually toggling
the "power on" lines. The guts of an ATX should easily fit into an
AT style PSU enclosure.
