nvme adapter for PBP

[Arwen]

An external GPU dock would be awesome sauce. You probably still need their fancy adapter with the carefully bent ribbon cable though.

Keep in mind it's only 4x though, so the GPU would severely underperform to its full potential.

Quantify "severely". I've been running laptop with eGPU via EXP GDC connected to M.2 slot, gaming was very comfortable.

And, from my reading, it's PCIe 2.1, meaning only 5Gbps per lane, (which includes high encoding overhead, not the lower overhead of PCIe 3.x).
That's perfectly fine & usable for a 4 lane NVME SSD. But, video?

Of course I could be wrong about the PCIe 2.1. (I thought I was wrong once, but I was wrong :-). Here is the reference;
