Or PCIe... I really would like to try building that.

I'm fairly certain you can't create a "mesh" with PCIe between multiple hosts. It's more like USB instead of Ethernet.
Don't treat the CPU board as the host but a peripheral. ;-)
But I'd say it's much closer to Ethernet than USB. You have controllers (routers), switches and nodes... USB doesn't, not like this.
