Don't forget to check out the "colored" plates on the back of the computers. Sometimes they are a thin plate of SS pop riveted to a plate of tin, real easy to separate with a straight edge. And the stand-off's where the motherboard screws to, sometimes are brass or SS. It all adds up eventually.
I had to think on this one awhile,,, too funny.since working in a maintenance depot for Uncle Sam's canoe club.
