Run a few "extra wires" through the RAM, NVRAM, CPU etc...  12V from the
PS should do it.  Otherwise a dedicated house line.
When the switch is activated the chips are hit w/ high voltage and the
HD is erased w/ the "device" (coil).

Maybe coating the chips and MB w/ a highly flammable hot burning
substance to melt them after the voltage hit...

It could be done.  It could all be erased within seconds given a big
enough coil on the HD.

Perhaps we should start the Psychotic and Paranoid Computer Users
Cookbook (PPCUC).
