[ale] PSU replacement

[Grady Harris]

Probably OT, but the machine I'm working on has always run Linux, when
it has run.

I need to replace the power supply in an ATX case. I've read through a
few how-to guides on the web, & it looks fairly straight-forward,
still have the docs that came with the system, including those for the
motherboard.

Haven't done this before, don't mess with hardware much. What could
possibly go wrong?

I mean that as a real question, not as bravado or a challenge to fate.
