With the Enermax CS-718 having the mainboard mounted in an inverted fashion, this means you get in via the opposite side panel as normal. Peaking inside, we see the painfully simple yet very smart Wind Tunnel Design. The Wind Tunnel connects two 120mm case fans on opposite sides of the case in such a way that the CPU cooler's exhaust is whisked directly out of the case's rear with minimal contact with the rest of the ambient air inside the case.
