Bought this to replace my main desktop rig a few months ago. Very pleased with the performance - photo and video editing is fast. I'm pushing two 4K monitors via mDP daisy-chained together, handles them both no problem. Power draw at max CPU utilization is right around 50 watts, at idle it's about the same as a normal CFL light bulb, or less. My electric bill is noticeably lower since using this system.
