In-Depth Information
we've mounted a motherboard, inserted all the screws, and connected all the
cables before we noticed that there was a metal tab sticking into one of our
USB or LAN ports. Before you secure the motherboard in place, verify that the
back-panel I/O connectors are mated cleanly with the I/O shield, as shown in
Figure 6-24. A bright flashlight can be very helpful here.

Make sure the back-panel connectors mate cleanly
with the I/O shield
Once the motherboard is positioned properly and you have verified that the
back-panel I/O port connectors are mated cleanly with the I/O shield, insert
a screw through each motherboard mounting hole into the corresponding
standoff, as shown in Figure 6-25. For the first two or three screws, you may
have to apply pressure with one hand to keep the holes and standoffs aligned
while driving the screw with the other.

Securing the motherboard
At times it's difficult to get all the holes and standoffs aligned. If that occurs,
insert two screws into easily accessible positions, but don't tighten the screws
completely. You should then be able to force the motherboard into complete
alignment, with all holes matching the standoffs. At that point, insert one or
two more screws into standoffs and tighten them completely. Finish mounting
