Thinking about put 3rd Folding Computer online, need recommendations

Ok,it appears (from some articles online) that at this time, most motherboards only offer pcie 4.0 in one pcie x16 slot.
I would have expected as much.
I read an article about a new b550 motherboard, that allows for 2 pcie 4.0 x16 slots, and now a latest that allows up to 3x m.2 slots at pcie 4.0 (x4) speeds.
No info on x1 slots.
It's still a bit of a grey area.

Well unless I go Threadripper or X299 mobo I am stuck with only 16 lanes right?

Affirmative

Now you know why I'm mostly using X99 & i7- 5930K --> PCIe lanes & reasonable used prices

Hmmm, an X99 MB,CPU,RAM deal here if interested. He is a solid forum member. https://forums.evga.com/FS-i75820K-MSI-X99S-SLI-Plus-Kingston-HyperX-32GB-RAM-Tons-of-watercooling-parts-m3017585.aspx

Intel Core i7-5820K

Has only [28] PCIe lanes - read the MB manual carefully - see if that would impact your plans, based on all the hardware your going to install & which PCIe slots are actually available

3 x99's w/40 lane cpu's and an x58 4x sli classy here. Older , cheaper hardware rocks right along for folding. My newest rigs are not as point productive and are used for other things now.

How about a x79 Asus WS board with a Xeon 1650 unlocked six core 12 thread. Low hours?
It has 40lanes

Since you only need 8 lanes on Windows (4 on Linux) for the most demanding GPUs, which run at 200-300W, 20 PCIE lanes (what I'm getting from my 9th gen I5 9400F with MSI MPG), allows you to run at ~750-1000W.
With newer GPUs this could become 1200W.

If you want an all in one system, where you can run 4 to 5 GPUs at x8 speeds, a Xeon or lower end Threadripper is probably your best bet.
I would go for older Threadrippers that have lower core count, but higher cpu frequency.
It could allow you (in theory) to run 4x 2080Ti (800-1200W) + 200W for the rest of the system = 1000-1400W at the wall;
with the possibility of expansion. Some of these boards can run 6 to 8 GPUs, topping out most breakers at 1600W.
