Corsair, best known for making memory and power supplies, has been manufacturing cases for some time now, but the Obsidian 550D is the first to grace our labs with its presence. It's a fitting choice as it's the only chassis in Corsair's catalogue marketed specifically as a quiet product. At first glance, the 550D has the look of a plain, closed, airflow-starved silent case. In reality, it incorporates a mix of noise reduction and performance features, giving it a hybrid nature reminiscent of the Antec P280.

The box.


Though the Obsidian 550D comes packed in an unassuming colorless cardboard box, it's nowhere close to a generic or budget case. Its current US$130~$140 street price places it at the higher end of the quiet case spectrum, in the same league as the Antec Solo II and P280. Aside from the usual styrofoam, there's also a bit of extra cardboard protecting the side and front door. It's a small gesture that we appreciate as we've received a few cases over the years with shipping damage.

The Obsidian 550D.

The 550D measures 19.5" tall and almost 21" deep with its overall size falling between the Solo II and the P280. It's a plain looking case aside from the brush aluminum door and the fan vent covers adorning the side and top. Like the Fractal Design Define R2/R3, it offers optional fan mounting points that can be covered when not in use to limit the noise exiting the case. The fan covers are attached using a simple push-to-release system (explaining the tape holding on the side cover during shipping) rather than unsightly screws. Notice the marks on the top right corner of the side panel — that was caused by sweeping away a small piece of dirt. The paint has a powder coated finish that is susceptible to smears and smudges.


The case accessories were contained in a small box stuffed into one of the hard drive bays inside the case. The included zip-ties, cable holders, and screws are all segregated and bagged separately. The 550D also ships with an internal USB 3.0 to USB 2.0 adapter, just in case your motherboard lacks a USB 3.0 header.
