[We don't cut corners (e.g. embedded controller, etc) and we use dc2dc which means that the BOM is higher.]
And I commend you for that, but I can also see why you are leaning towards sticking to larger form-factors for the future, where you don't have to even consider cutting corners in order to stay competitive and turn a profit. One thing that was clear from your SP20's is that you care about the quality of your product. It's a shame that the hardware becomes obsolete so quickly.
Is there any particular reason other than wanting to stick to a single model, rapid deployment for data-centers that you would not consider a larger form factor 3rd gen miner that requires external PSU('s)? For those on the small farm scale, it gives us an opportunity to save costs without being too much of a burden in setup.
