Just curious if you've looked at cost for Threadripper for the extra PCIe lanes. There's definitely a premium over mainstream processors, but they're also cheaper than server SKUs.
Generally I find the threadripper not worth it. Radically less motherboard selection, radically less chassis options, half the bandwidth, less pci-e, and near zero price savings.
I looked recently and found the epyc and TR motherboards from the same manufacturer within $1.00. The Epyc 7302P cost $450 for the CPU, cheaper than any TR. Sure TR has some options with higher clock speeds, but generally that's less useful for fileservers.
Generally TR made sense ... before AMD brought out the single socket Epycs.
