3.2 ESATA

You will find a SATA connector on a cable attached to the front ports. This internal SATA connector is designed to connect to a standard SATA connector on your motherboard. This will allow high-speed external hard disk enclosures such as the Antec MX-1 to run at the same speeds as internally installed hard disks.

3.3 AC'97 / HD AUDIO PORTS

There is an Intel® standard 10-pin AC’97 connector and an Intel® 10-pin HDA (High Definition Audio) connector linked to the front panel of the case.

You can connect either the AC’97 or the HDA connector, depending on the model of the motherboard. Locate the internal audio connectors from your motherboard or sound card and connect the corresponding audio cable. Consult your motherboard or sound card manual for the pin-out positions. Even if your system supports both audio standards, you may only use one connector.
