@dizmo Because it's just off the top of my head, you're overthinking this big time. Also, I don't have to put in quadros, because two 1080ti would absolutely smash those firepros in any workload, so who cares.
Another thing, the Intel PCI-e is WAY faster that the nvme drive, so you have the fast 400GB boot drive, the still pretty damn fast 1tb NVME storage, and 8TB of mechanical storage.
