IIRC, there are raised metal sections welded to the base of the XT case,
and it's into these that the plastic standoffs for the motherboard sit.
If I'm misremembering, ignore me...
Anyway, get yourself an angle grinder and slice right down the middle of
the raised metal sections from front to back. Hammer the remains flat,
so you've got a roughly flat bottom to the case.
Then, get yourself a scrap ATX tower case (free from all sorts of
sources) and chop the bit of metal out of that which normally holds the
ATX motherboard standoffs (I expect nearly all of them unbolt, no
After making a few strategic holes in the bottom of the XT case, you
should be able to bolt that assembly in the right place so that the rear
cut-outs for the cards line up with a fitted motherboard properly.
You'll then be able to mount any ATX motherboard that the original
sacrificial ATX case would take.
As for the PSU, good idea of someone's regarding mounting it inside the
original PSU - you'll want to keep that big red power switch! :-)
Connector panel - if the engineering stacks up (XT card slot holes don't
get in the way), I'd be tempted to cut out the whole relevant part of
the aforementioned sacrificial ATX case out and mount *that* inside the
XT case, bolting it to a suitable cut-out that you can make in the back
of the XT's case. Lot easier than trying to cut lots of neat socket
holes in the XT's steel.
The alternative would be to desolder the connectors from the ATX board
and relocate them via cables to brackets scavenged from relevant ISA
cards (soundcard, I/O card etc.) - but I don't know what your chances of
getting the parallel port socket off an ATX board without damaging
anything would be!
Normally I wouldn't agree with chopping an old machine apart, but it is
just a PC and not something particularly interesting...
