HotHardware.com posted a review on the Antec Three Hundred Gaming Chassis

Early last year, Antec launched their gaming line of cases with the Antec Nine Hundred - instantly garnering praise throughout the PC enthusiast crowd. Its main claim to fame was the complete openess of the front bezel, using perforated bays and 120mm fans to keep airflow rushing inside. Also notable was the expansive interior, bottom-mounted power-supply unit, and oversized "Big Boy" 200mm fan placed at the top that allowed some massive cooling over the CPU socket area. We were able to take a look at the Nine Hundred ourselves and were pretty impressed overall, although we noted there were a few things that could have used some improving.

Well, Antec is back at it again with a dual offering for this year. The Antec Twelve Hundred is a beast, featuring twelve bays and 6 large fans with two more mounts for installing additional units. Price, however, can be an obstacle as the Twelve Hundred sells north of $200 US. As a counterpoint, Antec has now released the Three Hundred Gaming Case. As its name might suggest, the Three Hundred is a pared down version of their Nine Hundred gaming case, that sells for less. It features six bays like the Nine Hundred, and includes some of the newer ideas used on the Twelve Hundred, but ships with fewer fans and accessories.
