Hehe! A by-product of the cheap manufacturing process - in a single process you can bend a sheet of mild steel and punch holes through it simultaneously. Such parts could be de-burred, but that increases labour costs as a part has to be moved to a different machine. Whilst I have cut my fingers on PC cases (and extruded door latches that are sharply cut extrusions), I was philosophical about it - after all, I had bought the PC after weeks of searching the dead-tree magazines for the most amount of MHz/ MBs etc for my money - so the inexpensive construction (an honest compromise) was my choice as a buyer.
By contrast, no user asked for an arbitrary curved plastic fascia that nothing more than an inconvenient, cack-handed attempt at product differentiation.
