I'm still surprised that it affects the machine at all though (unlike
say things like cutting holes in cases). It's just a screw (plus of
course it's rare to see a machine where the motherboard slot screws are
all original anyway). If it makes life easier for anyone responsible for
maintaining the machine, and it doesn't do anything that can't be *very
easily* put back, then I'm surprised it's seen as a big deal.
Particularly on this specific machine, which is common as dirt.

Maybe there's a whole class of machines that use these screws. This
IBM's the only one I've come across that specifically needs a certain
tool (that doesn't get shipped with the machine).
