The Maximus IV Gene-Z in all it's glory
Back I/O ports, we can see HDMI output, CMOS reset button, likely an ASUS ROG Connect port, as well as USB, E-SATA and audio ports.

About the board there can be seen voltage read out ports, X-Fi 2 SupremeFX audio, ASMedia USB 3.0 constrollers, Intel ethernet controller, open ended 4x PCI-e lane, POST80 LEDs, power and reset buttons, estimated 12-Phase DIGI+ VRMs on which AUS calls 'ROG EXTREME ENGINE DIGI+' and the list will likely go on as you would expect from a feature packed ROG motherboard. The ASUS Maximus IV Gene-Z will make for a very powerful mATX solution.
