This thread has kind of become a fail. I wanted to document my build to help builders who are unfamiliar with electronics, but my plans changed a little. I will buy a BeePre2 and move both the C2As and BP2 power transformer/supply into the C2A chassis and combine the rest of the components in the BP2 chassis. That's going to take a long time and a lot of money, but hey, you know how it's going. (might call it Bottlehead Heroin lol)
