NZXT has announced a new addition to its line-up of cases: the Beta EVO. NZXT says that it designed the Beta EVO due to the good response received about its predecessor, the Beta. The Beta EVO is constructed of steel and features four external 5.25" drive bays, a horizontal HDD cage and tool-less HDD installation. The Beta EVO also includes space for up to six 120mm and two 140mm fans. The case is pre-drilled for the easy installation of water-cooling set-ups. To keep costs down, the Beta EVO does not include any fans. The Beta EVO chassis will retail for US$50 and will be available for purchase in September.
