Well that's true. It's just there's something relating to hydraulics that
worries me. I know it'd different, but I just keep thinking too much
pressure = burst pipes.

When I did the //e supply my initial idea was to get a mini-ITX supply and a
smallish primary transformer to get the mains to a usable range. Those
supplies are costly though.
I did a bit more digging a little while ago and came up with a supply the
same size and shape as an XT one. It has yet another set of different
connectors. However I quite like this one. It uses a single main connector
one conductor longer than the IIgs supply, and the same spacing. If it
weren't for the cable lengths I'd just rearrange the header for
compatibility. Unfortunately it's a little short to be useful.
