2.6 Mounting the Motherboard
Before installing your motherboard, ensure that your chassis is fully compatible. The Tomcat
i915 S5120 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.
