In Figure 6, you can see the motherboard rear panel with keyboard PS/2 connector, seven USB 2.0 ports (black ones), clear CMOS button, two USB 3.0 ports (blue ones), optical SPDIF output, FireWire port, eSATA-300 port (green one), one Gigabit Ethernet port, ROG Connect button and independent analog 7.1 audio outputs.

No mouse PS/2 connector is available, thus you have to use a USB mouse with this motherboard.
The ROG Connect feature is quite interesting. It allows you to use the seventh USB 2.0 port from the rear panel (the one near the ROG Connect button) to connect your PC to another computer (a laptop, for example) through a cable that comes with the motherboard for overclocking and diagnosing your computer from the second computer.
Speaking of diagnosing, instead of a POST display Crosshair IV Formula has a series of four LEDs that indicate which component is failing when the computer is not turning on (see Figure 7).
There are several other smaller features targeted to enthusiasts. For example, all the connectors for auxiliary fans support PWM technology in order to automatically control the speed of each fan, and on three of them the motherboard supports the installation of a thermal sensor in order to control the fan speed according to the temperature on where you installed the corresponding thermal sensor.
In Figure 8, you can see all accessories that come with this motherboard.
