Step 3: Your almost there.
After your remove the guts(and do what you please with them) put the plastic piece holding the screen on that you removed in the last step and put it bake onto the monitor piece.
Now take the stand off of the bottom of the monitor. Then remove the very bottom of the stand that is sits on the desk and remove it from the slider/adjustment piece.
Then drill a hole through the very middle part of the stand(most should have a circle in the middle already) big enough that you screw can just barely make it through.
