Did you save any of those thin metal boxes AOL was mailing their
CDROMS in a couple years ago? They look to be just thick enough for
some small SMD designs.

Not the thin ones. About 8 years ago, the Bank of America chain
was handing out "Christmas boxes" of AOL material (including CD)
which were at least an inch and a half deep. Unfortunately, the
box lid folded over the edges of the main box part and that did
not make a good enough metal-to-metal contact along the edges.

The tin-plated steel tea and coffee boxes have plastic-paper
lids (throwaway) and the lip at the top will support a metal
or PCB cover that can be ***-metal-screw secured in place.
Better raw material for a box to shield RF in my thinking.
Solderability is great anywhere on the surfaces, good for
making connections to the can "ground."
