I got a sff P330 Xeon with integrated graphics for ~$500 two years ago that includes case power supply etc. Far faster than an n100 and even lower power than if you added a GPU to an n100.

I just plugged in a kilowatt to check:

My Lenovo sff workstation running Plex idles at 15 watts- which is 90% of the time. Streaming 4k 52Mbs hevc (This Flash Gordon is my torture test that caused me to upgrade 2 years ago) it’s 18 watts! I was so surprised that I went back and unplugged the Ethernet thinking I put the killawatt on the wrong server.
