Does anyone know if this kind of connector works with a PCIe to M.2 adapter? i.e. I have a PCIe card with an NVMe drive connected, could this be used? My motherboard doesn't have an M.2 slot.

I don't see why not, but in that case you're better off using a 10 GbE PCIe ethernet adapter. Cheaper and no internal wiring.
