The Guru of 3D published a review on the MSI Z170A Gaming M9 ACK
A quote from the article:
We review the MSI Z170A Gaming M9 ACK. The luxurious big brother of the M7. It is one of the best looking products if you ask me, dressed for success and with added benefits like USB 3.1, multiple M.2 slots and the fastest DDR4 support the product will impress. It also comes with extended looks, AC WIFI, a VRM that can be liquid cooled and then a dozen or so other features.MSI Z170A Gaming M9 ACK Review @ Guru3D
