Provantage has 10 x X13SAE-F for sale right now at ~$477: PROVANTAGE: Supermicro Motherboard-X13SAE-F-O Supermicro MB Motherboard-X13SAE-F-O W680 LGA1700 No Memory ATX
Disappointing that Supermicro seem to plan no variants with DDR4. 128 GB of DDR5 ECC will probably make this financially less competitive.
Looks like it's going to be a while before I replace my Xeon v3/v4 systems with their crappy old 40 PCIe lanes
you can desolder the PCI slot or just ignore em. there is no processor PCIe lane stolen for it.
The real gripe here is that there should be another PCIe slot here instead of the PCI slot.

and the x8 only x4 instead then ? where to get the PCIe lanes ?
some need PCI hardware that is accessible at lower adresses like 80 hex.
impossible at PCIexpress Cards.
thinking about pulling the trigger but can't find any DDR5 ECC for sale
if you wait for DDR5 ECC UDIMM available i bet the boards are out of stock or price doubled.
Availability of everything out of China can be very poor, just look at all the new Q1 2022 lockdowns they are initiating. This includes ports, read stuck containers. Less supply with some given demand, higher price of course. But I don't see those boards sell for 900.
Another interesting question is how about IOMMU groups of Alder Lake with W680?
And another question is, are those x4 slots on X13SAE-F indeed x1-only from chipset, or are they Gen 3 PCIe x4?

Between the processor and the chipset, there are plenty of PCIe lanes, but every motherboard manufacturer so far is choosing to use the reference design with all PCIe slots coming from the processor and none from the chipset.
The Supermicro X11SRA I just bought has a PCIe 3.0 x4 slot that is connected to the chipset, which gives you x16/x16/x8/x4 slots. Plenty for a GPU and two storage cards (HBA, M.2 carrier, etc.) and some other card.
The block diagram in the manual says yes, they are only PCIe 3.0 x1. With the x8 DMI 4.0 connecting the CPU and PCH, you really aren't going to bottleneck much, so I'm a little puzzled why the PCH doesn't have more PCIe connectivity. And, if you do bottleneck, it's likely the 2x M.2 on the PCH or maybe a PCI 5.0 x8 HBA. All the rest of the hardware hanging off the PCH barely makes a dent compared to those.
The two x16 form-factor slots are PCIe 5.0, but share 16 lanes, so you get x16 or x8/x8. This would make a great base for a storage server with 2x HBA that use PCIe 5.0 x8 slots, and on-CPU video. Each HBA could handle 4x M.2 or U.2 at PCI 4.0 x4 speeds, so 10x NVME total (plus one for boot). You could use the on-board SATA for spinning capacity.
If you find a deal on RAM, let me know. Close to pulling the trigger myself. Their Tested Memory List is pretty barren, I can't even find their listed ECC stick for sale, and DDR5 ECC is pretty rare overall to start with.
