The Corsair Obsidian 250D ships in a compact cardboard package with an image of the chassis and some marketing text on the front. Turn the box around and you will find a blow-up diagram and some additional information. Both sides of the package hold a list of specifications and two more images of the Obsidian 250D.
Two foam spacers hold the enclosure in place, while a plastic bag has been put over the chassis to protect it from scratches and fingerprints.
You will receive the manual, an assortment of all-black screws, and a few cable ties. While this may not seem like much, it is all you will need—even if you fill the 250D to the rim.
