Most energy efficient fully functional computer to run BI?

Wanting something that can handle 12x 1080p cameras at 15fps all motion triggered. Was thinking this, but not sure it can handle it: https://smile.amazon.com/gp/product/B017OF6T9O/ref=ox_sc_sfl_title_2?ie=UTF8&psc=1&smid=A1BVYXEL822RF0

i currently have an i5 3570k, 16gb, ssds, and win 10 pro. I am using a graphics card amd 270x, which I may not need from what I have read. Any suggestions on curbing the 24x7 power draw? I'm only using 42% cpu so maybe under clock a bit and lower cpu wattage?

Other suggestions?

remove the card and use hardware acceleration. Have you measured the draw?
All in ones are a terrible idea.
