So....how hard is it to remove a hash board from this bad boy?  I have an RMA with bitmain and I need to remove one of the boards to ship to China to have it looked at.  At least the other two boards are hashing me around 3 TB so I'm not dead in the water.  Doesn't look like the heat sinks are having issues since it was fine for about 24 hours when I initially plugged it in and then the board just stopped hashing completely.  But I'll know more when I pull it out.
