If your estimates of the number of MiniMig boards out in the wild (100-150) are close to accurate, you might have a hard time reaching your minimum order number needed to go into production. Getting 33% to 50% of the MiniMig owners to purchase your case would be quite a marketing accomplishment.
I was concerned about your project from the beginning when it was evident that the cost of the finished product was going to be over $50
I still hope that as more MiniMig boards are built and ACube sells more completed boards, that you will find enough buyers to recoup your development costs.
