You're right, and it was a mistake that all that wasn't shared from the beginning. But I can relate to them being overwhelmed, we've felt similarly and our case has been anticipated for over a year now 
Projects and crowdfunding campaigns are as much a sequence of lessons as they are commercial efforts on the part of creators. Mistakes will always be made. What really matters, ultimately, is if you change and adapt to them.
This new-found receptiveness is a pleasant sign of Dune Case heading in that direction.
I'd strongly consider doing this if you have the resources (which you'll need a lot of, probably $100,000+, to do this). You'd be able to go much, much further with this design if you could adapt the power supply to fit within the abnormal shape. Further, since you're limited to a single graphics card anyway, a ~500W power supply would be enough for practically anyone.
(You'd also be able to offer additional value to customers - and capture more revenue - by bundling the power supply with the case in this way, so the consumer-side economics are also good.)
The caveat, at least with what I know about the industry, though, is that you'd have to be selling a lot of cases to make this work. Many thousands at least, and probably more. Plus, scaling to that volume would be a very tough challenge given the design of the enclosure - you don't have obvious methods like stamping to "grow into".
