The IBM Personal System 1, stylized as PS/1 (which came after the PS/2 line, because of course it did), is a modular system that used add on "units" to expand the system. I've seen two-stack systems before, but never a three stack one. Check out the listing HERE.

A couple more photos for posterity:





Looks like the top unit is strictly for the expansion bus- there's a sound card in there. Bottom one might really just be for the 5.25" disk drive, which is kinda strange given the PS/1's heyday was at the end of the 5.25" floppy era.
