an area where you can freely work.

cover toward you and lift it away from the

Remove Processor Card
Remove the current processor card (Figure 3) from
the Processor Card Slot and set it aside. Be careful!
The heatsink on top of the processor card can get
extremely hot if it has not been given sufficient time
to cool. The location of the processor card varies
with each Power Computing model. For the
PowerTower, refer to Figure 4-Label A; for the
PowerTower Pro, refer to Figure 5-Label A. On some
models (usually mini tower and tower systems) you
may need to remove the support bracket/fan
assembly (Figure 3) to reach the processor card.
