2.6 Mounting the Motherboard
Before installing your motherboard, ensure that your chassis is fully compatible. The Tomcat
i7221 S5150 motherboard conforms fully to the ATX specification. Your chassis should
include preinstalled mounting posts that match exactly with the mounting holes in the
motherboard. Lay the motherboard on top of the mounting holes to ensure that all the
necessary mounting posts exist in your chassis and that they match the mounting holes on
the motherboard.
Some chassis’ include plastic studs instead of metal. Although the plastic studs are usable,
TYAN recommends using metal studs with screws that will fasten the motherboard more
securely in place.
See the diagram below for some examples of typical motherboard fixing studs.
TIP:
Use metal studs if possible, as they hold the motherboard into place more securely than
plastic standoffs.
