Raspberry Pi 4 PCIe bridge “chip”

Is there an ARM based board in a ITX/ATX form factor with a few PCIe slots? Because that's what I'm looking for.

This PCIe on the Raspberry Pi is a neat hack, but still a way of from being a real desktop.

SolidRun MACCHIATObin has one PCIe slot. Enough for a GPU! I have this, it's pretty good. Though I have to resort to USB-Ethernet since FreeBSD doesn't support the onboard NIC (and the driver isn't the easiest to port) :D

SolidRun HoneyComb LX2K has a bigger full size slot and an M.2 slot. I don't think bifurcation works but you do have two slots, you could run a GPU and a NIC or HBA at the same time, using an M.2 to PCIe-slot adapter. And/or use extension boards with PLX switches if you need more cards?

$750 is perhaps a bit more than I was willing to pay, but that is pretty interesting.

Not ITX or ATX, but the RockPro64 has a single PCIex4 slot. $60 for 2GB model or $80 for the 4 GB model right now.

This is at a completely different budget, but I used an Nvidia jetson TX2 dev kit for a while and it's reasonably responsive and has a PCIe slot. I think the dev kit carrier board is also ITX-shaped, but am not too sure.

Only if you have deep pockets.
