Three Hundred Illusion the Versatile Case

The Essentially Cool and Quiet Case

Impressively spacious and unbeatably reliable, the Antec Three Hundred is an unbeatable enclosure. Despite its eminently portable frame, the Three Hundred has enough room for an NVIDIA 8800 series graphics card, as well as six hard drives and a standardATX motherboard. A cable management compartment keeps your system organized and the airflow unobstructed. A 120mm rear fan and 140mm top fan ensure that the case runs cool even when playing the most demanding games, while the sleek black finish gives it an extra stylish edge.
