Summary: The computer has been nothing but trouble. Bought it Aug of 2012. The machine would freeze every once in a while. Forced to shutdown hard. Sure enough after a while started receiving a Blue Screen of Death. Called support and they recommended to reset BIOS to factory Default. That yielded nothing. Reloaded the OS from the recovery partition and that also didn't fix the issue. I researched the BSOD codes and it pointed to a hardware problem.
Summary: The eject button for dvd drive and the hardware volume control buttons did not work. Returned day after receiving it. I did see another review for the 27 inch version also had same problem. Update1: The replacement Asus I received works great and I'm very happy with it. UPDATE2: I've had this All-in-One for one year and one month. The fan just went bad. Its out of warranty and Asus has no repair manual. Asucks.
