FCC shielding. IMHO unless you're working in a hospital or somewhere else that could possibly be sensitive to this sort of thing, toss 'em. They just trap heat and cut your fingers when you open the system up to work on it. But don't tell Scuzz that, I seem to recall he had a whole thread a few months back about how those metal shields are the greatest thing next to sliced bread. :lol:
