Hi I certainly agree that, say potting the circuit board, would be a lot easier than some of the stuff we have been talking about.
My main concern about tearing up the unit is impacting the magnetic shielding. I assume that the outer enclosure forms part of the magnetic shield (at least that's what the data sheets say ...).
