Have you seen the honeycomb lx2? It has 16 cortex a72 cores @ 2.0 GHz, USB 3.0, quad 10G Ethernet, PCIe, and supports up to 64 GiB of DDR4-3200 in SODIMM format. Performance wise it’s around a x86 quad core from a few years ago.

It $750, but it’s the only thing that comes to mind. There’s a $1000 variant that adds 40 GbE support.
