from completed build FaceRipper - mATX X399 SLI Build

The first mATX Thread Ripper board to hit the market, the build quality on this thing is amazing. An abundance of m.2, SATA, fan headers and 3 x 16x16 PCI-E slots, this thing is a beast and ideal for a full-fat SLI set-up with a 1 slot spacing for improved air-flow. My only gripe is that some of the bios options are not documented too well. Although the majority of options are self-explanatory for the average user the more in-depth 'enthusiast' options could use some more documentation. The fan tuning UI is also a little clunky, but it does the job. These are relatively minor criticisms for a fantastic board.

This is my third Asrock mobo and I can say that I am a fan of asrock after using them for over 2 years. Plug and play. Easy bios update function and was able to detect everything the first time around. Happy camper.
