Aesthetically, the Corsair Obsidian Series 550D cuts a handsome figure, thanks mostly to its clean lines and a diamond-cut aluminum front panel. The aluminum front panel conceals the optical and peripheral expansion drive bays and is held in place by magnets. Another unique thing about the front panel is that it can be open in both directions thanks to a cleverly-designed hinge system. Also behind each panel, you'll find a generous amount of sound dampening foam to help isolate noise.
While only the front panel is aluminum, the rest of the panels are put together using stamped steel that have a matte and brushed feel. It doesn’t look nor feel tacky and all in all, the combination of materials here makes the Corsair 550D look and feel like a premium product.
