I'm not sure what sort of certification process this unit went through but it didn't go as far as booting the computer. No display, no lights on the keyboard, groaning wheezing fans (to begin with) then full speed fans, still no display, still no USB. Totally useless. The unit was nice and clean and came with unexpected mouse and keyboard as well as power cord. Visually it was super (apart from a missing card slot cover). Totally useless though.
