Likes to lock
This board is OK if you NEVER plug in a USB or SATA device while powered on. I'm not sure if it is the BIOS or hardware, but this board will lock up the OS frequently when hot-plugging a device. I RMAed the first one in hopes that it was just a bad board. The second board behaved a little bit better, but still locked up once a day. RMAed that one for a different model. Problem solved. Also, Be aware that ASUS will not acknowledge that their board has a problem unless you replace EVERYTHING else (CPU, Memory, Power Supply) first..

Great Motherboard
I wanted a good looking board with eSata on the back and USB3 support. Great documentation. Easy to setup. Completely plug-and-play with Windows 8. The included utilities are a little awkward, but work great. This one's a winner.
