For servers at sky-high prices only.

For $699, your closest choice might be the NVIDIA Jetson AGX Xavier... PCIe 4.0 but with a x8 slot, and an NVMe M.2 x4 PCIe 4.0 slot too.

SolidRun HoneyComb has about the same slots and price, but instead of weird nvidia closedness you get first-class upstream EDK2 support, everything is about plug & play with ACPI.

The HoneyComb is at PCIe 3.0. Sadly it's at ARMv8.0 (w/ Cortex-A72) so that removes it from consideration totally for me.

And the Xavier has an official-but-still-beta EDK2 firmware available too, which includes ACPI support and can even boot Windows. (https://developer.nvidia.com/embedded/downloads#?search=UEFI...)

Yes, GPU 3D acceleration is currently not supported there yet, but the LX2K doesn't have a GPU at all anyway...
