If I have a problem I assume I can add shielding to the wires, or buy some nice shielded ones somewhere?
Most of the gen3 and 4 cables like the ones Ian's using are already shielded. The old style ribbon cables that worked with Gen1 are too noisy to work with Gen3 and later for anything other than a few cm in length.
I've used m.2 to PCIe3x16 adapters from ADT-Link with success to feed 6 GPUs from a single Ryzen 3 CPU but that was in Folding@Home where low to mid-range GPUs can be kept fed with minimal to no loss in performance from a PCIe3 x4 connection. I just "bi-furcated" one PCIe3 x16 slot to x4/x4/x4/x4 and installed a 4 x m.2 Adapter and used the other 2 PCIe3 x4 m.2 slots on the motherboard (one from the CPU and the other from the chipset)
Today I will try for a "dry fit" to see if shoehorning the target system into my current Phanteks case is even possible.
I have a Phanteks vertical GPU card kit that is currently driving the 3rd slot GPU.
A "dry fit" means I won't be committing to try to install it in the case today. Just sit the major components (without cabling) in place to see if it "fits".
I am ignoring the "might get too hot" elephant in the room for now.

Corsair XB looks like it must be a "Cooler Master HAF XB EVO"
Corsair EVO same as the XB above?
Corsair Air 540 cases ~$159 at NewEgg.
CoolMaster is also refreshing the EVO line and has released the HAF 700 EVO but a recent review has indicated the MSRP is purportedly $499USD. A bit too flashy for my taste.
Building dual-GPU systems that live in the unfinished portion of my somewhat dusty basement I've still found the heat in even airflow optimized cases to be difficult to deal with. I usually replace the supplied case fans with Noctua iPPC fans and use two sets of fan profiles one driven by the CPU temperature controlling the front top ingress and rear exhaust and another driven by the top PCIe x16 slot temperature driving the middle and lower front intake fans. Even then the lower card tended to heat the upper card quite a bit even with all the rear slot covers removed. The only way I could achieve reasonable (<= 70C) temperatures for the GPUs and CPU was to use Hybrid GPUs for the upper cards to remove the heat directly. My favorite case is the Fractal Meshify S2 which is still available with all steel side panels but just a little small for your use-case unless you were willing to remove the PSU shroud which would require drilling out rivets.
Thermaltake X5, listed on Amazon but "not available".
Thermaltake Level 20XT cases. NewEgg ~$249

So Keith, which one of the above that I can find are you happiest with?

Never used the HAF XB EVO and I always thought it rather poorly used its available space.
I was always very happy with the Corsair Air 540 cases. I also have two Corsair Air 740 cases.
Main reason for the upgrade was the limited 240/280 rad capabilities of the 540 case which was remedied by the 740 case which can mount a 360 in the front. But I like the 740 less than the 540 other than the front 360 rad capability.
And since my focus has been to move from air to water cooling, larger cases that allow such have moved me to Phanteks 719, Enthoo Pro 2 and the Thermaltake cases.
I was most happiest with the TT Core X9 but since they don't make that anymore I also use the Level 20 XT which is basically the bones of the X9 but with glass panels.
Since you only do air cooling for your cpu and gpus, the Air 540 case would be a good solution I think. The only case I listed that still has 5 1/4 bays for optical drives in this day and age also. Also has two 3 1/2 hot swap hard drive bays in the bottom of the case which makes for simple drive maintenance.
All of the cases I use only need blowing out once every 3 months or so. Never had issues with dust or debris on the motherboard. Only dust is in the rads usually.

I meant for the USB cables for the PCI-express to USB to PCI-express risers. I guess it depends if the shielding is to stop interference from outside the cable, or to stop crosstalk between wires inside it. But there's only one data wire inside I think.
Interesting what you say about Folding at Home. I was told over there you need more lanes than Boinc projects, and also more lanes for GPUGrid. I was assuming biology projects tended to have more data flowing to and from the CPU?
I love the word bifurcated (and even trifurcated). These words should get used outside of astrophysics, eg. Glaswegian accent: "See you?! If you do that again, I'll bifurcate yer skull so I will!"

As long as the elephant doesn't mind noise, you can always add more fans. I find it best to leave 2 inches between the fans of a GPU and something else though, or the air can't get in easily.
