Single Board computer with minimal price and power consumption?

Advise single Board computer.
Requirements linux, ethernet, low power consumption and price, the rest is not important.

UPD: Need a version where there is no video processor, USB and other things. Roughly speaking, only the CPU, RAM, ROM, or card slot and an ethernet port.

Also in the search.
At the moment inclined to odroid c1+
But this is the "full" version with the corresponding power consumption. And Yes, interesting project as an alternative to the rpi - kacie14 commented on July 9th 19 at 13:12
