I forgot to add that we drill the holes in the back and bottom of the cabinet. After filling the "dead chambers" with expansion foam, we install hardwood plugs in the holes. This makes an attractive solution.

Hardwood plugs are available at most hardware stores. They're usually available in many sizes, and I prefer to use the 1/2" diameter plugs. They're essentially 1/2" dowel rods that have been cut into 3/8" length sections. That's another way to create plugs for exotic woods - if premade plugs can't be found.
