Antec 900 PC case ATX Full Big Tower, black

The Antec Nine Hundred was one of the most recognizable high-airflow cases of its time-known for its open design, aggressive cooling, and expandability that let builders push hardware harder than ever before. The new Antec 900 is a modern interpretation of that legacy.
