I had the chance to check out the super case at the Doepfer booth, and it was very cool indeed. If you were to fill it, you'd have some investment going financially, but it does allow you to get a very sophisticated setup in an easily portable frame.

My understanding is that you can, depending on the kinds of modules you choose, determine how many PSU's you'll need for each section. The fewer, the lighter the case...
