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.
