1. Bundle the neck cables to one side (as shown).Supporting the base, remove the two black screws (circled below) that connect the neck to the base assembly.

2. Carefully feed the neck cables through the hole in the Faraday cage. Important: The Faraday cage is very heavy and has sharp edges; handle with care.

3. Pull the outer shell (with Faraday attached) away from the neck. Note: There is no need to remove the outer shell from the Faraday unless you are replacing the outer shell. If you are removing the shell from the Faraday cage, go on to the next step.

4. Note: Perform this step only if you are replacing the outer shell. Remove the three screws in the base of the Faraday cage to separate the shell from the Faraday cage.

Replacement Notes:

Faraday cage: Look at the exploded view diagram during reassembly. First, attach the metal neck plate (the round, metal plate with holes) to the top of the Faraday cage, this is keyed. Next, install the Faraday cage into the top plastic housing, and replace the three screws holding the plastic housing to the chassis. Thread the neck cables through the hole in the metal neck plate. Attach two neck cap screws to connect the neck to the chassis. Then route the neck cables correctly in the base and replace the cap neck spoke retainer and three remaining cap screws.

Warning: Whenever the bottom housing is opened for service, you must do two things:

  1. You must clean the original thermal film from the surfaces joining the thermal interface layer and reapply thermal paste to the thermal pipe.
  2. You must tighten the four torx screws on the bottom housing to a minimum of 17 in.-lbs. If you do not have a torque driver, you will have to make sure these screws are tightened by hand FIRMLY, BUT NOT FORCIBLY. Or, purchase the service tool (076-0899) in order to ensure the thermal pipe is firmly mated with the top base. If the bottom housing is not securely attached to the base in this fashion, the CPU may overheat and become damaged. Failure to follow either of these steps could cause the computer to overheat and damage internal components.

Refer to the topic, "Thermal Paste Application" for detailed information.
