Triple K80 - Parts for a Remote CAD PC

[Sentein]

Okay i have a GPU based 1u server case hanging around (3 GPU Unit). I was thinking about what i could do with it. Right now i have 3 K80 and 2 M40 at the house from some experiments i was trying out. If i toss Windows 10 on the hardware and remote into the OS to design, is there a good way to utilize 3 GPUs for CAD and Blender rendering? I need 1 Windows PC in the house and i would rather this be the only one. I am unsure of how to get the Multiple K80 to be used correctly by blender, Inventor or Solidworks. I do alot of CAD work so the CAD would be a better start if i only could get one working. Any info on getting this to work in windows would be helpful. I am not looking to invest in any extra hardware as i feel i have plenty already. Thanks for any responses.
