Remove the PC Board and you are left with a power supply that is suitable for many things (or remove if not up the job), plus there is a BNC connector on the back side plus a spot where the GPIB connector poked through which can be repurposed for a D connector suitable for the task at hand.

They have lots of ventilation holes, unlike the clamshell A/B switches which tend to be thicker metal (didn't need stamping for rigidity) with fewer holes. If I need a DB-25 or DB-9 hole... the A/B serial switches are real attractive because most of them have that kind of holes and sockets in them already.
