Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fit different types of
chassis. Make sure the location of all the mounting holes for both the
motherboard and the chassis match. Although a chassis may have both
plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure the metal
standoffs click in or are screwed in tightly.
Then use a screwdriver to
secure the motherboard onto the motherboard tray.
Warning!
Make
sure you lift the
lever completely
when installing the
CPU. If the lever is
only partly raised,
damage to the
socket or CPU may
result.

IMPORTANT!
Please note that special, new silver heatsink retention clips must
be used with all Xeon 533 MHz FSB (front side bus) 604-pin processors.
These new retention clips have “604P” clearly marked on them. Using the old
clips will not keep the proper amount of pressure applied and may cause the
processor to overheat. You should not use these new retention clips with
Xeon 400 MHz FSB processors (even if the CPU socket is 604-pin) as they will
too tight and damage the CPU socket.
