The most resounding question asked at CES 2017 after showing AM4 motherboards before launch is ?Where are the ITX motherboards??. That is really all you need to know about how popular ITX options are these days. Especially since it was not possible on AMD's AM3+ platform with FX CPUs and definitely not going to be possible with AMD TR4 Threadripper motherboards. It is not just about the small size, but the power too. That is why there wasn't as much demand for mini-ITX FM2+ compared to AM4, because the new Ryzen platform actually has competitive crunching power vs Intel's offerings.

For their part, Gigabyte now has the AB350N-Gaming WIFI ITX motherboard for Ryzen. It uses a B350 chipset instead of the ITX-specific A320 chipset to give builders better headroom when it comes to performance through overclockability. The B350 chipset also provides all the necessary modern storage connectivity including PCIe x4 NVMe M.2 and USB 3.1 Gen 2 support. Coupled with Gigabyte's custom audio implementation and RGB LED features, the AB350N-Gaming WIFI packs a lot on a tiny package and a sensible $115 price tag.
