Speaking of machined parts versus something else...

Anyone notice how commodity PCs have screws that have clearly
been *cast* onstead of *turned/Machined*? Everytime you thread
one into a hole, you generate a nice supply of metal shavings.

Not good.

To get back on topic, when did this trend start? The IBM PC,
PC/XT, and PC/AT used machined/turned fasteners. Lots of classic
non-consumer hardware used various "captive mechanisms" instead
of plain old screws and bolts.

And how about sharp edges inside a chassis? Older hardware tends
to have spent a little time in the hands of a whitesmith, who
added lots of finishing detail like smooth edges that don't cut.
