Obsidian Series 450D has an elegant brushed aluminum front panel and a solid steel body, with an interior that’s optimized for efficient, high-volume airflow. But don’t let its mid-tower size fool you – the 450D can also house some serious watercooling gear. The included dual front AF140L intake fans provide direct GPU cooling, and there’s a total of seven fan mounts for your extremely high volume airflow projects. All air intakes are protected with removable dust filters. The interior is designed for superior cooling efficiency, with a modular removable drive cage system and dual SSD bays that mount behind the motherboard tray and out of the airflow path. The extra-large, flush mounted side window puts your system-building expertise on display while keeping with the sleek and refined Obsidian Series design.
