If you have not heard of Antec before you must be living in a cave or somewhere remote. Antec is one of the major players in the case and power supply market. At one time or another many of us have used one of the cases. The Sonata line started all the good stuff and then came the Performance One series that includes the likes of the P180 which was very popular. Then there was the release of the Nine Hundred which was one the best air circulating cases on the market mostly due to the huge 200 mm fan on top.
