If you've followed what goes on with the ASRock model numbers, you would know that the -M refers to the board using the mATX Format. The mATX boards from ASRock, though, don't only bring with it a smaller board, they also bring with it a cheaper price and at the time of writing the ASRock Extreme4-M is the cheapest X79 motherboard available at Newegg, coming in at $218.99 US.
It will be interesting to see how the cheapest X79 board performs today. Before we see how the X79 Extreme4-M performs, though, we need to check out the package and bundle to see what ASRock are offering us in that department; once we've done that we'll take a closer look at the board before we move into the BIOS.
