What is the potential of a d-1xxx series xeon as a mixed/consolidated-workload desktop?

Required I/O:

  • Four or more USB-TypeA
  • dual Gigabit Ethernet
  • Two physical PCIe slots, of any size

Tasks may include:

  • Secondary-GPU Rendering
  • Single-thread C/Java/Python Compiling (in a ramdisk)
  • High-speed Networking (likely ethernet over infiniband)
  • Thunderbolt connectivity (more ‘nice to have’ really)

The Datto NAS boxes I’ve seen, look somewhat promising, & I’ve noticed there are single-board cluster solutions, but I’m just not sure of much w/ these platforms.
Any tips or pointers welcome!
Thank you!
