It is important to note that many other configurations of the cutout 140, including the shape, location and depth of the cutout 140, are possible consistent with embodiments of the present disclosure. For example, instead of extending from a top surface 112 of a board 110 through to a botton surface 114 of the board 110 to create an opening 141 (or vice-versa), the cutout 140 may be only partial ly extend through a depth of the board 110 starting from a top 112 towards a bottom 114 surface of the board 110, or vice-versa, to create a hole.
