Perfect, I have the 5 cards on 1x to 16x risers of course powered via sata cables for each riser card.  Look forward to learning something new.  Thanks!

Oh wait, one more dumb question.  My MB has only 2x PCIe 3.0x16 and 4x PCIe 2.0x1.  The risers are 1x to 16x, will that be ok to run 5 FPGA's this way or would it cause stability issues in your opinion.  Thank you again.
