I mean with VM-leaking things like Spectre (not sure how much similar things affect ARM tbh) having physical barriers between your CPUs can be seen as a positive thing.
As a learning tool, having the ability to build a real hardware cluster, in a MiniITX case is awesome. I do sort of wonder what the business case for these boards are, I mean are there actually enough people who want to do something like this... schools maybe? I still think it's beyond weird that that there are so much hardware available for build Pi clusters, but I can't get an ARM desktop motherboard, with a PCI slot capable of actually being used as a desktop, for a reasonable prices.

That's roughly 80% the performance of my current x86 desktop.
