I haven't watched that anime yet. I also never even came close to the real thing.
What I do know is that one popular picture of the black X68k alongside a matching monitor and keyboard are to me the embodiment of the cool industrial/utilitarian late 80s computer design. The computer tower case looks like some premium stackable industrial equipment. The only thing I can think of that achieves similar iconic level is the PowerMac G5 "cheese grate" tower.
