this board concerns me due to the low CPU speed.
I would look into the Gigabyte GA-Z77N which is being utilized by a couple others in the forum. This motherboard has built in wifi, bluetooth, SATA 6Gb/s, and USB 3 ports, about as future proof as you can get.
I realize you are looking for low power, but you should be able to spec a processor that will still allow the M3-ATX to work.
4G of RAM is a bit overkill, 2G would be fine, but RAM is cheap, except in hibernation speeds.
