This looks like a good group buy. I guess I'm only wondering one thing: the payment confirmations don't show who ordered the miners, correct? The blockchain info shows that they were paid for. It seems like the images just show that someone, somewhere ordered and paid for some miners.
Forgive this rookie question, but how are we to know that YOU are in control of the account (or accounts) that paid for the miners? Are you able to send signed messages?
Nobody else has asked this question, so I'm sure I'm missing something obvious. And, I know you had John K. look at your identification, so I'm not questioning you are who you say you are. Just trying to learn more than anything.

I understand your concern but where can you get some nice receipt like that?

If you wish some additional proofs simply PM me or post here
If you really want to, we can go with the same confirmation procedure for unit #1 or you can compare output addresses from first and third order by yourself
