a heat sink removably connected in contact with the stiffener, the heat sink having a base defining a groove, wherein the tab extends into the groove when the heat sink is connected to the stiffener;
a first circuit board disposed within the interior, the first circuit board positioned between the stiffener and the heat sink; and
a second circuit board disposed within the interior, the second circuit board positioned between the cover and the stiffener,
wherein the cover, stiffener, and heat sink are stacked along the transverse direction, and
wherein the first circuit board comprises a plurality of computing components and the stiffener further includes a plurality of fingers, and wherein the first circuit board contacts one or more of the plurality of fingers.
