After removing the front cover, evenly pull from each corner to pull apart the left side and right side of the case.
This step is easiest if you take time to not fully remove the right side cover immediately but instead pull each corner a little amount and repeat as many times as necessary to prevent bending or damage to the interior metal frame.
After removing all silver and 10 mm black screws attached to the console frame, remove the fan by pinching the grey and black wires at the same time. Detach the wires from the port.
If they are not removed at the same time, the risk of wire tear or breaking the proper connection to the port increases.
there are a couple of screws missing from the guide around the (what i assume would be) the black wifi antenna and some screws holding the metal shield from the mother board
