Hey, bought 3 G431-MM0 servers (natural habitat of MJ11-EC1), doing some modifications, so they can feed my OCP v1 GPU server's 3x80A power.
4x SXM2 V100 16GB, baby!
That means, I will not need the 10x PCIe Backplane boards.
If someone needs a CPBG8A0 Backplane board for 10x PCIe using the MJ11-EC1, let me know, I have 3 of them for sale, shipping worldwide.
50 eur+shipping/each (SAS cable not included, I'll still need that, cheaper then ebay.
If you really need it, I could give you the empty 4U server case (without HDD bay, PSUs) too, but that's heavy, so shipping would be very expensive.
