Step 5
Mount the Mainboard on the Computer Chassis
You may find that there are a lot of different mount-
ing hole positions both on your computer chassis
and on the mainboard. To choose correct mount-
ing holes, the key point is to keep the backpanel of
the mainboard in a close fit with your system
case.
After deciding on the proper mounting holes, po-
sition the studs between the frame of the chassis
and the mainboard. The studs are used to fix the
mainboard and to keep a certain distance between
the system's chassis and the mainboard, in order
to avoid any electrical shorts between the board
and the metal frame of the chassis.
(If your computer case is already equipped with mounting studs, you will
need to tighten screws to attach the mainboard.)
Note : In most computer housings, you will be able to find 4 or more
attachment points to install mounting studs and then fix the main-
board. If there aren't enough matching holes, then make sure to
install at least 4 mounting studs to ensure proper attachment of
the mainboard.
Step 6
Connect Front-Panel Switches/LEDs/
USBs/1394a/Aux-In/Mic-In/Line-Out
You can find there are several different cables
already existing in the system case and origin
atinting from the computer's front-panel devic
es (HDLED, GLED, USB4/5, Aux-In, Mic-In,
Line-Out, 1394a devices etc.) These cables
serve to connect the HDLED, GLED, USB4/5,
Aux-In, Mic-In, Line-Out or 1394a connectors
to the mainboard's front-panel connectors
group, as shown below.
