The MSI X299 Gaming M7 ACK motherboard features a black PCB with a black chrome overlay covering the board's heat sinks and rear panel cover. The chipset overlay has fingers that extend in between the PCIe x16 slots in the areas just under the two PCIe x1 slots. Further, there is a plastic overlay protecting the audio components above the PCIe slots. MSI integrated LEDS into the rear panel cover, the VRM heat sink, the chipset cover, and the audio cover for a unique look. The board is designed around the Intel X299 chipset with in-built support for the latest Intel LGA2066 Skylake-X and Kaby Lake-X processor line and Quad Channel DDR4 memory running at a 2667MHz speed. The X299 M7 Gaming ACK can be found in retail with an MRSP of $399.99.
