Keep the PCI cable short. ISTR PCIE is only specified for 300mm and
that includes the tracks on the boards. I had a similar adapter that
broke out 1x mini pcie to 4xPCIE (using a PCIE multiplexer chip). It
came with a 400mm USB3 cable and I had some reliability issues until I
used a 200mm cable. This particular setup was pushing that poor 1x
lane to it's limits as I had 4x NVME drives hung off it. The Mesa
cards use a tiny fraction of the available bandwidth so they should be
a lot more tolerant.
Having said that, Linus Tech Tips managed to get PCIE to go 3 metres
though it was a little flaky.

Perfect! Will do.
