Caution. By cutting this flange (and drilling the holes in the next step), you will defeating a safety feature of this unit. In the case of internal leaks, or a water spill by the filler neck, water may now not be captured by the deck, and would be able to flow down onto the electronics area.

If you wish to retain the water retainment safety feature, install the 3-way switches differently, or use switchless fans.

The 3-way switch will be positioned so that you can use a pencil point poked through the grill to change the setting after your ChiliCube is re-assembled.

You can use a dremel tool to cut part of the flange surrounding the deck. Position the switch and mark, it will be just behind the grill on the front-side of the cube when it is upright.
