Long Flexible M.2 to PCI Adapter?

JohnSmith2 · January 9

I have an MSI X670-P Wi-Fi motherboard with the following layout:

Currently I have the OS boot drive in M2_1, and two 2-slot GPUs in PCI_E1 and PCI_E3. I would like to add a PCIe 3.0 X8 networking card, and I'm OK with it running at X4 speeds, but X2 speeds are a little too slow. Given there are extra M2 slots on the board, I think it should be possible to convert one of them to a X4 PCIe slot. The only problem is M2_2 and M2_4 are completely covered up by the GPUs, and M2_3 is partially obscured by the top GPU. Even if I moved the boot drive to one of the lower M2 slots, the CPU cooler (Noctua NHD15) covers up M2_1, so I couldn't use an adapter there either.

I have seen some adapters, like this one (https://www.amazon.com/ADT-Link-Extender-Graphics-Adapter-PCI-Express/dp/B07YDGK7K7), with a long cable, but it doesn't look like it would be very flexible. If it is long enough, I feel like maybe it could go in M2_3, twist out around the GPUs, and then fit in the case's slots that are beneath the motherboard; but maybe that is wishful thinking. Here's a picture:

Do you have any suggestions for how I could get this to work? Are there M2 to PCI converters with long, thin, and flexible cables (so I can easily route them around the GPU)? Or do those not exist?
