You can always water-cool the GPU, with big radiators. I have no idea about how to do it in 4U, I personally just use off the shelf consumer hardware (mini-ITX, small PSUs, short GPU, etc.) and 3D print the cases. ~10 cm height is perfectly achievable with custom cases and PCI riser cables.

There are no riser cables that are stable for PCI-Ev4.

  I’ve never heard of this. Can you explain why? (I don’t use riser cables FWIW)

    I’d imagine the parasitic capacitance becomes more of an issue at the higher frequencies of v4.

    Higher frequencies are more susceptible to interference, especially if you have long cables. A short 2 inches riser, surrounded by a grounded metal sheet, might work.

  LINKUP sells them - I have 7 for a home server. Up to 50cm for v4 and I have a couple v3 because they go up to 1 meter. https://www.amazon.com/gp/product/B0898QMCLS https://www.amazon.com/gp/product/B0898QMCLS
