Summary: Right around the time the warranty ran out, the fan started having issues. It will seize up and cause the unit to overheat and shut down. Upon examining the inner works, it is obvious that the fan is placed too close to stationary parts and cannot turn freely. And there is no fix for it.
Summary: Sent this machine back 3 times in the past 4 months. Each time I was without a computer for 1 1/2 weeks. I kept describing a loud sound and sudden shut down (sounded like a bad fan to me). The first couple of times, they refused to check the fans but replaced the hard drive twice.
Summary: Major design flaw on this unit. The adjustable arm it rests on is spring loaded and the glass over the monitor is thin and shatters. I had mine set up completely vertical and while touching the screen it slightly rocked back causing the spring to slam closed.
