I'm still working on it! At first I was going to use a new off the shelf enclosure, but they are not as off the shelf as promoted by the manufacturer as evidenced by a lack of extruded aluminum cases here.  
 
I sent copies of the original DS5 plans out to get some quotes to have a replica made (with a few changes, like a modular line cord). I will update when I get the details back about delivery.

Make one with an IEC C-15 cable (is that what you mean by modular line cord, like your preamps use?) and I want one. For real.
