ECS showed off its the H110S-2P, a no-frills motherboard built in a form-factor that's smaller than mini-ITX, although compatible with mini-ITX cases. The board lacks add-on card expansion slots. The only expansion you can give this board is an mPCIe, and an M.2 2230, which closely passes over the PCH. You can tell from the M.2 placeholder marking on the PCB running over the PCH that even the production board could lack a PCH heatsink.

The H110S-2P supports 6th generation Core processors in the LGA1151 package, and up to 32 GB of dual-channel DDR4-2400 memory though SODIMMs. Storage connectivity, besides the M.2 slot, includes one SATA 6 Gb/s port. Display outputs (you'll need them), include one each of DisplayPort 1.2 and HDMI 1.4a. Four USB 3.0 ports, and two USB 2.0 ports complete the package.
