That's pretty cool. I have an IBM PC (I believe it's AT class) that has
been tempest-proofed. It's a case-inside-a-case design, with an internal
case where all the hardware mounts to, and then an external case that is
the Farday cage. The ports on the back of the inner case are extended to
poke out the back of the external case, and there is shielding on the
back panel.
The IBM badge on the front says "TPC 4 System Unit" and the Type is 4459.
Maybe someone can look that up.
I must have talked about it here before because I have pictures already on
my server:

I can't remember if I actually checked what's on the hard drive or not.
See Marvin's follow-up message to that posting. He has one to.
