bag for storage.
12 Disconnect each remaining cable from the system board, including the
front I/O panel connectors and the rear fan connector.
13 Remove the seven screws that secure the system board to the case.
Three screws are aligned top-to-bottom on the left side of the system
board, three are aligned top-to-bottom near the center of the system
board, and one screw is located near the middle of the right side of the
system board.
14 Lift the system board away from the case by raising the right side of the
system board about one inch.
15 Slide the system board about one inch to the right (toward the front of
the case), then lift it out and away from the case.
16 Slide the new system board into the case. Make sure that the ports align
with the port openings in the back of the case and that the seven screw
holes match the screw holes in the case.
17 Replace each of the seven system board screws you removed previously.
18 Attach all cables to the new system board.
19 Place the processor into the processor socket. Make sure that the
processor is aligned correctly by matching the small triangle on the corner

socket.

press the processor retention lever back into place.
Caution
The heat sink has Thermal Interface
Material (TIM) located on the bottom of
it. Use caution when you unpack the heat
sink so you do not damage the TIM.
21 Place the heat sink over the processor, lining up the four captive screws
with the four posts surrounding the processor.
22 Loosely screw in the captive screws on the corners of the heat sink, gently
tightening diagonal screws (screw in one screw, then the screw located
diagonally to the first screw). Do not fully tighten one screw before
tightening another.
23 Gradually and equally tighten each captive screw until each is firmly
tightened. Do not over-tighten the screws.
24 Connect the heat sink fan’s power connector to the system board.
25 Reinstall each expansion card.
26 Replace the side panel by following the instructions in “Replacing the side
panel” on page 147.
