Well, tonight I stripped the PSU down and there aren't any filtering
caps, at least not the X type ones I'm familiar with. Instead the
mains cable plugs into a honking big sealed tin box that terminates in
a 2 inch earth wire and 2 spade connectors that the live and neutral
hook up to. Said earth wire is bolted to the chassis and joined to a
similar bolt holding the fan to the case.
Anyone seen something like this 'mains plug in a sealed tin box'
arrangement before?
Yeah, it's a sealed (and probably potted) power-line EMI filter. It
should have some filter caps and coils in it.
Assuming the extra power-line noise you get by removing the EMI filter
isn't a problem, that's probably something that you can try bypassing,
to see if it's the source of your problem.

I think
it's gotta be a ground-fault that's causing Witchy's
problems.
I am almost sure it is.
