5 stars because I'm easy to please... its a tiny FF dektop that works fine. No issues thus far.I know its a refurb unit and its probably close to 10 yrs old but, their quality control could be a little better. The fan was full of dust and the SSD had 3 dents in the case, and some restock scribble on it.  Even still, it booted up and ran fine.  For $130 bucks I wont complain too much.The listing says its an M900 however when I opened it up it is actually an M910 model.  Other than some minor style differences in the layout of its guts, thats not a big deal.The wifi is a cheap dongle that was included, not internal. The USB ports are not blue, but the system checker says they are 3.0 super speed.  The back of the unit is not the same as the pics on the listing. There is no rear mic jack and there is an added VGA port.  Again, probably just due to it being an M910 and not a n M900.  Minor differences.The keyboard and mouse are your typical cheapo items that work perfectly fine.I replaced the included SSD with a new kingston SSD and loaded linux mint on it, which runs very well on this unit.Don't hesitate to buy one, you get more than ya pay for.
