Motherboard Pin Layout
Connecting the Audio Ports (AC’ 97 and HDA)
The case has both an Intel standard 10-pin AC’ 97 connector and an Intel 10-pin
HDA (High Definition Audio) connector. You can connect either the AC’ 97 or the
HDA connector to your motherboard depending on the spec of the motherboard. If
your motherboard supports Intel’s standard onboard AC’ 97 audio connector, plug
the AC’ 97 connector directly onto the board. If your motherboard supports Intel’s
High Definition Audio, plug HDA onto the board. See instruction below:
Pin Assignment for Audio Ports (HDA and AC’97)
Locate the internal audio connectors from your motherboard or sound card. Consult
your motherboard or sound card manual for the pin-out positions.
Connecting the eSATA Port
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.
