I have bought 2 antminer s7's on ebay and they both seem to be doing well. I do notice that one of them seems to have a loose board in the middle. When I go to unplug a 6 pin pcie from the middle hashing board the board moves upwards a little. Is this normal? How are these things held together in there? I have all o's and my temps are normal so I am just curious if anyone else has noticed this?

Yes, i had exactly the same with my B1, but it was the right board. Hashing was not affected in any way. Just be careful connecting the PCIe connectors. Hold the board with the other hand when disconnecting, I would suggest.
Incidentally, why did you buy on ebay paying 400-500 more when they are available here for less?
