Proving that a standard mid-sized tower isn't the same as an obsolete tower, Antec's SLK 1650 comes to bat. Housing three 5.25" and two 3.5" external drive bays, it hasn’t forgotten the internal hard drives that are so necessary today, leaving space for three 3.5" internal drives. It also gives easy access to the ports for two of your USB 2.0 devices up front. This case makes cooling a literal breeze. It comes with one 120mm fan located in the rear of the case for exhaust, a side vent for your CPU, and a vent in the front that can easily be converted to house an additional van.
