I possess a Samsung 970 EVO Plus NVMe SSD set as my primary Windows storage. I'm uncertain about the optimal slot choice. Would the lower one be better? You think it's more suitable because it's farther from the GPU and CPU, possibly keeping the SSD cooler? I also have a Samsung 860 EVO 2.5" SATA SSD available. You mentioned the top NVMe slot turns off two SATA channels—should I install the NVMe drive in the lower slot to avoid that, since it doesn't disable any SATA channels?
Regarding performance, it shouldn't matter. What's important is the clearance to ensure you can reach the NVMe drive after installing your GPU. Edited May 25, 2020 by TofuHaroto Typo
The primary version is built for this use, but others might lose speed when you're handling several drives at the same time (the overall data rate reaches the limit at PCIe 4.0 x4 the chipset can handle)
Yes, you're understanding correctly. The top lane is managed by the CPU, while the bottom lane comes from the chipset.
The guideline affects the chipset of the mobile card. It limits the number of PCIe lanes based on bandwidth. When it reaches its maximum capacity, adding more load will reduce both write and read speeds. I might be mistaken, but it seems all X4 lanes come from the chipset, not the CPU.

It's the Intel board (I left out the AMD ones, which use Crosshair). Then it doesn't matter because all M.2 slots link to the chipset, sharing the PCIe 3.0 x4 connection (Intel calls it DMI 3.0) with the CPU.
