I think the Jetson AGX Xavier is probably a better match out of the box to the requirements than anything listed on that page. The only thing it doesn't meet is the plus on 16+ GB of RAM. For the same price you could get a much better x86 desktop though.

- 8 core CPU

- 16 GB LPDDR4x

- Volta based GPU

- Gig ethernet (native)

- PCIe x8 (x16 physical slot)

- m.2 E key (PCIe wireless or LTE)

- m.2 M key (PCIe NVMe SSD)

- 2 USB 3.1

- HD audio header

- eSATAp through PCie bridge (allows native 2.5" SATA drives)

But really there isn't really much reason to use ARM on a desktop outside of needs relating to specifically needing to have ARM.
