Before the Raspberry Pi came out, one cheap and easy way to get GPIO on a computer with a real operating system was to manipulate the pins on an old parallel port, then most commonly used for print…
I guess you might want to link the psu to a bunch of relays that controlled by the gpio, and use it to deliver medium amounts of power to various peripherals. i guess lots of motors or maybe fairly powerful led lighting arrays, or weak heaters , comes to mind.
So what seemed most daft to me is exposing the 3v and 5v lines on that breadboard like thing, but not using the psu’s +/-12v lines - that could let you run 12 and 24V stuff. plenty of space to allow for a bunch of relays and some connectors.

But even so its a strange form factor for that.
