Motherboard Pin Layout
CONNECTING THE eSATA PORT
This case comes with an eSATA port in the front of the case to connect to your
external SATA devices. You will find a SATA connector on a cable attached to the
front eSATA port. Connect it to a SATA connector on your motherboard.
CONNECTING THE AUDIO PORTS (AC’ 97 and HDA)
There is an Intel standard 10-pin AC’ 97 connector and an Intel 10-pin HDA (High
Definition Audio) connector. You can connect either of them to your motherboard
depending on the specification of the motherboard. See instruction below:
Note: Please check your motherboard manual for your audio header pin layout and
make sure it matches the table below. Even if your system supports both audio
standards, you may only connect one connector not both.
Pin Assignment for Audio Ports (HDA and AC’97)

of the case.
