It look like ASRock really wants to you build an awesome mini-ITX system as they have revealed the world’s first mini-ITX socket LGA2011v3 motherboard! Yes that means you can pop in an eight-core Intel Core i7-5960X processor and DDR4 memory into a mini-ITX build! The new board is the X99E-ITX/ac and is a standard mini-ITX motherboard with a good amount of its PCB taken up by the large LGA2011v3 socket.
The socket itself actually features a unconventional cooler mount which is much like the 2088 pin socket that you would find on Haswell-EP system boards. ASRock includes their own cooling solution for this board which is a copper heatpipe powered aluminum heatsink. It will be interesting to see how well it can cool a 140W TDP Haswell-E chip.
One thing that you will notice about the board is that it only has two DDR4 DIMM slots, ASRock has to make this sacrifice due to space limitations. So the board only supports dual-channel DDR4 memory, even though the platform supports quad-channel memory.
As far as storage goes you have one 10 GB/s SATA-Express, Ultra M.2 (PCIe Gen 3.0 x4), a eSATA 6 GB/s and four SATA 6 GB/s ports. Expansion includes a single PCI-Express 3.0 x16 slot and one mPCIe 3.0 x1 slot that holds the boards 802.11 ac WLAN + Bluetooth card. Other connections include two Intel-made Ethernet ports, 2-port USB 3.1 controller (type-A ports), four more USB 3.0 ports, two USB 2.0 ports, a PS/2 port and 8-channel HD audio.
ASRock did not announce pricing or availability.
