Power consumption is 18 Watts, 20 Watts under load with one ethernet port active.
When compiling, the temperature rises from 55 degrees to 66 degrees, but so far it never went above that.
For each ethernet port you plug in, power consumption jumps with about 3 Watts. In total the machine has never consumed more than 30 Watts which is still fine to work reliable as fanless. The touch of the case is hot but never up to a point where the machine becomes unreliable. I would not stack another machine or phonebook on top of it though ;)
The CF slot is located on the bottom of the board, which is kind of unfortunate as you need to unscrew the board to access it ;-(
