I recall seing a picture of it long ago in someones online album. It was a 
separate 19 inch box a few RUs high with at least one pcb and a jumble of 
wires :) Obviously in some sort of development stage and I'm not sure it 
was working at that point.

I think it might even be the compaq rackbox shown here:

Of course this is just speculation :)
