Since its unveiling at Computex 2009, the Obsidian Series 800D has served as the mac daddy of Corsair's enthusiast chassis. After focusing on delivering more affordable variants over the last two and a half years, the company is prepared to trump its venerable flagship with a new offering: the Obsidian 900D.
Designed for system builders who want a spacious premium enclosure and don't mind paying for it, the "super tower" Obsidian 900D offers room for up to 10 expansion cards, nine storage drives (or up to 15 drives in total with extra cages that are sold separately), four 5.25-inch devices and two power supplies.
The 900D's product page is currently scarce on details and pictures, but it seems like two three-bay drive cages can be mounted directly below the 5.25-inch bays, while another trio of three-bay storage cages can be installed in the bottom chamber, though doing so might prevent the use of a second PSU.
The enclosure supports motherboard form factors including ATX, E-ATX, XL-ATX and HP-ATX, while it can accommodate up to two 480mm radiators and two 240mm radiators as well as 15 fans. The 900D's stock cooling configuration includes four fans: three 120mm units up front and one 140mm unit in back.
Three of the case's drive bays are hot-swappable, while other features include the obvious: fan filters, tool-less assembly, a CPU heatsink cutout as well as ample holes for wire routing. Reports from CES say that the case measures 25.8 x 27.3 x 9.9 inches and will cost about $349 when it ships early this year.
