So that limits how far down you cut. The upper area runs into some of the hidden sections where the cowl and fresh air vent meet. And it's pretty close to the outer edge, as well. Probably to avoid getting into the areas previously mentioned. I'll post another pic of the fan block off patch panel, maybe giving you a better visual.
