Verdict

The MSI Z170I Gaming Pro AC is a high-end Mini-ITX motherboard built for 6th Generation Intel Core processors (LGA1151) and the Z170 chipset. Key specifications include support for up to 32GB of dual-channel DDR4 memory with OC speeds reaching 4200MHz, an M.2 slot located on the back of the PCB supporting 32Gb/s PCIe Gen3 x4 speeds, and integrated 802.11ac Wi-Fi with Bluetooth 4.2. Its main pros are the isolated Audio Boost 3 technology with a dedicated headphone amplifier, specialized gaming LAN for low latency, and a thoughtful layout that places SATA ports near memory slots for easier cable management. However, notable cons include an M.2 slot limited to 60mm length, which excludes common 80mm NVMe drives, a lack of USB 3.1 Gen2 Type-C connectivity, and slightly more modest overclocking headroom compared to larger full-sized ATX boards.
