ASRock's X99 Mini-ITX was one of a kind, and with the advent of Intel's X299 chipset, ASRock once again breaks the monotony of full-sized ATX motherboards and shrinks the HEDT X299 platform for small form factor (SFFPC) builds. The X299E-ITX/ac has many advantages over its predecessor. For starters, you get three M.2 slots for drives, quad channel memory (albeit SO-DIMMs), a nice VRM, and even a custom water block you can buy separately. In fact, after working with the motherboard, I highly recommend buying the Bitspower full cover block if you plan on heavy overclocking, as it also cools down the VRMs. Without further hesitation, let's see what the X299E-ITX/AC has to offer.
