Hmm, yeah, the latest cheese grater seems to have x4 PCIe 2 slots (other than the GPU one). That gives you gross bandwidth of just 16 Gbit/s, which is well below the 40 offered by USB4 Version 2.0 (what a great name).

The 2019 has PCIe 3, so that’s already 32 Gbit/s, but it also has multiple x8 and x16 lanes if you really want to go nuts (and if there’s a vendor offering an appropriate card*), so there’s plenty of future-proofing there.

* I’m not sure how far-fetched it is to homebrew this kind of thing. You can have someone print the board for you these days…
