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.
3.4 Power Switch / Reset Switch / Hard Disk Drive LED Connectors
Connected to your front panel are LED and switch leads for
power,reset, and HDD LED activity. Attach these to the corresponding
connectors on your motherboard. Consult your motherboard manual
for specific pin header locations. For LEDs, colored wires are positive
(+ ). White or black wires are negative ( – ). If the LED does not light
up when the system is powered on, try reversing the connection. For
more information on connecting LEDs to your motherboard, see your
motherboard manual.
Note: Polarity (positive and negative) does not matter for switches.
There is also no Power LED in this case. The illuminated case fans will
turn on when there is power to the computer.
