Cons
Con BIOS issues
The UEFI BIOS have not been updated fully to fix all known bugs. Users have reported double boot issues as well as poor mouse input in the BIOS itself.
Con Odd color choice
While the board may look black in color in pictures, up close you can see that it is actually brown. While not a huge issue, those that do like to match their color schemes of components may have a hard time finding anything that really goes with this brown color.
Con Not the best onboard sound
While the onboard sound is serviceable, a dedicated card will sound much better. This can often be the norm for a motherboard, but there are boards out there wil quality built in sound, this is just not one of them.
Con Poor SATA placement
The GPU will cover some of the SATA ports making them inaccessible if a GPU is used. That means the GPU will have to be taken out in order to gain access to those ports, either to add a new drive or unhook one already plugged in.
