Anandtech ASRock X99 M-ITX board

*The worlds heaviest breathing ever!*
There is bundled dual-stream 802.11ac wifi, along with dual Intel network controllers and SATA Express. USB 3.1 is also supported through two Type-A ports, presumably using the ASMedia controller we previously tested on other motherboards. The box also mentions Ultra M.2, which means PCIe 3.0 x4 lanes for an M.2 slot and looking at the board it seems to be located between the socket and the SATA Express ports. With all those PCIe lanes to spare, it makes sense to use them in this fashion.

Man I want this board. The only shameful things is only 2 DIMMs.
Note how it using a different Socket pitch.
For 2011 there is Standard and Narrow and this board uses the Narrow pitch for the CPU Cooler

I really dislike how close the Inlets/Outlets are to the mounting points, it looks like you would have massive limitations on fitting choice. I would have moved them all towards the center by about 5-10mm each.

Yeah it is indeed limiting, but on the other hand it's typically SFF :)
