The board also has "Intel" slathered all over it and although it's certainly not the DTK, it's definitely some kind of Intel-based system.
I'm with G in that it's probably just a regular PC case missing its plastic skins. Custom-built PCs often use motherboards that don't exactly match up with what the case offers, especially if somebody overbuys a case or buys it with the intent to later install bigger cooling hardware, or just has a case already and puts whatever board they can put into it for free. Not every seven-slot case has a seven-slot board installed.
As for the fact that it has a similar optical drive ot Macs? was apple the only company that uses Matsu/Panasonic mechanisms? Alternately, Apple had switched to IDE by then. Any reason that a PC built by somebody scrounging for parts couldn't have used an optical drive pulled out of a G3?
My verdict is that it's a PC built as cheaply as possibly, whether or not the case itself is interesting or if better/more pictures will reveal that it was a common PC case, who knows.
