Over the weekend I started building the case for this power supply. It's a 4U Computer Server Case that I got for $70.00 off Ebay from NewEgg. I gutted it completely and using some aluminum angle stock I made some pseudo rails. Using bits from the guts that came with the case I was able to 'stack' the dsp-1200fb's so that air can flow around them a bit, and still gives me room for other things require to operate this power supply.
Here's some Photos of where the project is now. Everything is still rough as I'm just test-fitting all the bits and pieces still. But you'll get the idea.
