If the boards can be successfully cloned with all same components, etc. can you guys think of a reason why you wouldn't be able to just flash the firmware and have fully functioning unit? 

I reached out to a couple of you privately to no avail so I'll just put this in the open, for those of you who have taken out a hashboard and examined it,
seen the components or can make photo or list of components, can you share that?  Some of you speak as though you're seriously interested in doing this but it's hard to see if it's just a hobby or challenge game, or if you're really interested in doing this in a bigger way. I'm interested in the latter. 
If you prefer to keep a hobby and no interest beyond, and you have a hashboard you'd sell me so i can have it examined, great, let me know.
