ASRock achieved the impossible, by innovating the world's first socket LGA2011v3 motherboard in the mini-ITX form-factor, letting you give your mini-ITX build the muscle of an eight-core Intel Core i7-5960X processor, with DDR4 memory. The new X99E-ITX/ac from ASRock is a standard mini-ITX motherboard, with a bulk of its precious PCB real-estate occupied by the large LGA2011v3 CPU socket. This socket features an unconventional cooler mount, which is comparable to the 2088-pin socket found on "Haswell-EP" system boards. ASRock has included an copper heat pipe-fed aluminium fin heatsink with this board, although its ability to cool a 140W TDP chip looks suspect.

A major sacrifice ASRock had to make, to achieve this contraption, is halve the memory bandwidth. Due to space limitations, the board features only two DDR4 DIMM slots, and will support only dual-channel memory, even as the platform supports quad-channel memory. Storage connectivity includes one Ultra M.2 (PCIe gen 3.0 x4 physical layer), one 10 Gb/s SATA-Express, an eSATA 6 Gb/s on the rear panel, and four other SATA 6 Gb/s ports. Expansion slots include one PCI-Express 3.0 x16, and one mPCIe 3.0 x1, holding the board's included 802.11 ac WLAN + Bluetooth 4.0 card. Two gigabit Ethernet interfaces, both driven by Intel-made controllers, a 2-port USB 3.1 controller (type-A ports), four other USB 3.0 ports, and an 8-channel HD audio make for the rest of it. ASRock didn't announce pricing or availability.
