Now we need to remove the lagsields that held the CPU down and the two large screws the cpus rest on.
The lagshields have holes through them you can use to turn them if they are too tight to turn otherwise.
Once all of the lagshields are the two screws are out, we need to remove the power supply. There are four screws on the bottom of the computer and two inside.
Now you can remove the cover and unplug the power supply. It has 3 connectors.
