if you are still trying a year later, the front LED is held to the fan assembly with some adhesive below the LED, you can just either pull it off or use a pry tool to get it off

Something worth noting for anyone doing this is first time many of the cables will be held down with adhesive tape, so you will need to remove the tape before some of the steps, mainly removing the midframe.

also my quest didn't have the 3.5mm hex screw for the motherboard in it for some reason.
