Provided are electronics chassis having air inlets with increased cross-sectional area that facilitate airflow through the chassis and thereby provide improved cooling. As electronics chassis are often stacked, it has been determined that the upper surfaces of a lower chassis may be utilized to at least partially define the air inlet of the upper chassis.

Likewise, the bottom wall of an upper chassis may be removed. When stacked, the air inlet of the upper chassis may be disposed above the truncated portion of the lower chassis. In such an arrangement, the size of the resulting air intake is significantly increased.
