Very pleased with the look and performance. heard complaints about the 5Mhz Wifi but is works great for me even with being 40+ feet away. When it first starts up the RGB's blink red like you messed something up but its just the way they have it starting up. Could be any other color to not scare first time builders. Just think you would be spending $30 bucks on Wifi in a system but this one already has it.

Amazing motherboard for the price, with plenty of features. The LED is a nice touch, and the built-in WiFi and bluetooth was awesome.

This is motherboard is one of the best in this price range. It's built well, it comes with some nice features, it has a good selection of I/O, and it look's pretty good. The power delivery also is pretty good. It's not a fancy board but there's not much to dislike about it.

Looks great, bios is easy, WiFi and Bluetooth work great. The RGB LED is a nice touch.

from completed build FIRST BUILD - NOT RGB FOCUSED

Great mobo so far. the wifi and bluetooth saved me money. i wish the lights on it would be a bit brighter but that doesn't bother me.

I chose this motherboard because it opens up the possibility of overclocking later on, and it comes with wifi. The price I got it for proved to be more efficient than buying a mobo and a wifi card separately. I realized after almost finishing the build that the USB 3 header was broken on mine, but I just bought a USB 3 card with a header for like $15 on Amazon since I didn't feel like taking everything apart again. Took two stars off because of this problem, it was really annoying.
