Installing the Motherboard
The sequence of installing the motherboard into the system case depends on the system case you are using and if you are replacing an existing motherboard or working with an empty system case. Determine if it would be easier to make all the connections prior to this step or to secure the motherboard and then make all the connections. It is normally easier to secure the motherboard first.
Use the following procedure to install the I/O shield and secure the motherboard into a system case.
Be sure that the CPU fan assembly has enough clearance for the system case covers and that assembly is aligned with the vents on the covers.
Installing the I/O Shield
The motherboard kit comes with an I/O shield that is used to block radio frequency transmissions, protects internal components from dust and foreign objects, and promotes correct airflow within the system case.
Before installing the motherboard, install the I/O shield from the inside of the system case. Press the I/O shield into place and make sure it fits securely. If the I/O shield does not fit into the system case, you would need to obtain the proper size from the system case supplier.
