Giving three stars because the first one I received had intermittent video card issues that caused the displays to work sometimes, other times not. I re-seated the card (which appeared to be loose) and that seemed to help, but then the problem surfaced again so I took it back. Ironically the second unit I received was inferior as well, but just cosmetically. The removable left-hand panel had been smashed in like someone hit it with a fist (the box was perfect so I assume this happened on the production line); luckily no interior parts were in harms way, so I decided to keep it because all else was fine (and Best Buy stepped up and gave me an additional $75 discount). If we're just talking about performance on the second unit, it deserves five stars. Flawless so far and very quiet (which is a must for me!).
