All,

Another idea that may have already been suggested is to cut pieces of
blank PC board to size, and solder them together to fit inside the
plastic box.  Again, this is okay for onsey twosey type things, but for
production quantities, it would be difficult at best, and not really
practical.

Old fashioned cake or biscuit tins may also suit this role. The main
part of the tin may need trimming down to a suitable depth, but for a
one-off could be ideal. May also be able to get rectangular versions
that might suit some form factors better.

Another "ready made" one to remember is the zinc alloy boxes made in the
UK. 
These come in similar sizes to many of the smaller plastic boxes, and
are very easily machined.
