Bought to replace Shuttle based on the Atom, too light for my uses. Everything I tested correctly under Linux (Debian testing). Contrary to what the previous comment, I have had no problem choosing the source boot. There are four USB ports, not 2 or 3 as shown elsewhere, and two slots for RAM.
Disadvantages: A gigantic light blue circle on the upper side; impossible to sleep in the same room, even in standby because the circle starts flashing slowly.
