The middle section of the aluminium front panel is floating like a speaker grill over a high-end speaker to improve airflow, and the front also features four USB 3.0 port, two USB 2.0 ports and HD audio ports.
To give you an idea of the cooling capacity of this case, Corsair says the system on the image below contains 23 Corsair Airflow series fans (22 SP120s and a single AF140), as well two 480mm radiators and two 240mm radiators! The case will also feature dust filters with a magnetic mounting system.
Water cooling enthusiasts will be happy to know that you can install two 480 mm and a 360 mm radiator inside this beast without the need for any modifications. For those concerned with aircooling, the 900D case comes with three 120mm fans mounted in front (Corsair Airflow SP120's). The middle section of the front aluminum fascia is "floating", like a speaker grill over a high-end speaker for improved airflow. If you look closely at the image above you'll see that there is about an inch gap oneach side, and the panel is nearly two inches away from the front fans, which gives them plenty of room to intake cool air.The Obsidian 900D is expected to hit the market later this quarter. The pricing is unknown but Corsair revealed it's not going to be priced to compete with the Little Devil, Case Labs or SilverStone's TJ11 cases because the 900D is not 100% aluminium. The MSRP of the Corsair 800D is $299, so $350 to $399 is likely a good guess for the pricing of the 900D.
