The ASRock X299E-ITX/ac Motherboard Review
 

Our next X299 motherboard review shrinks down from the large ATX and E-ATX sized motherboards to the sole Mini-ITX offering for the X299 platform. The ASRock X299E-ITX/ac is a diminutive board that offers nearly all of the same features as its larger counterparts but in a package well suited for SFF systems. Users will find four SO-DIMM memory slots for quad channel operations, dual Intel NICs, six SATA ports, three M.2 slots (!), plus integrated Wi-Fi and Bluetooth capabilities.
