Gigabyte has a pretty interesting board. This new ITX board is based on the INTEL H67 chipset. While most ITX boards only has one HDMI port, this has two.
Both ports are HDMI 1.4 compliant which is capabale of devliering 3D contents. So you can in fact playback the contents via the 2 ports, one to a projector while the other to a 55″ LCD HD screen.
Other connectors at the rear include audio ports, analog and digital SPDIF, D-SUB, 2 HDMI, 2 USB 3.0, 4 USB 2.0 and 1 eSATA port. Below are pictures of the board GA-H67-USB3.
