Mini-ITX motherboards have been extremely popular over the past couple of years. So much so that many case manufacturers have created special cases just for the form factor that have become some of their best sellers. Typically Mini-ITX motherboards have been reserved for mainstream systems, recently we saw many impressive Z97 Mini-ITX motherboards. But what about Intel's HEDT (High-End Desktop) platform? Because of the size of the CPU package the thought of having an X99 motherboard in the Mini-ITX form factor was unheard of, until ASRock released the X99E-ITX/ac. They were able to fit the LGA2011v3 socket onto a Mini-ITX form factor and still have room for quite a lot of other features. The only real downfall of this motherboard is that you are limited to dual-channel memory and you have to use ASRock's included proprietary CPU cooler, which we will get into a bit later in the review. But this board packs in ASRock's OC socket, a SATA Express port, Ultra M.2 slot, Wireless 802.11ac + Bluetooth, USB 3.1, ASRock's Super Alloy design and much more! Let's see what this tiny, yet powerful motherboard is all about!
