Packaging and Accessories:
One is packaged in a fairly plain cardboard box, and it is clear that no extra money was spent on making the packaging pretty / colorful. The front of the box presents a picture of the case, while also confirming the model number and that it features USB 3.0 support. The back side offers more details on the design of the One, as well as providing a listing of the various specifications.
Like most cases, the Antec One is packed in a plastic bag nestled between two large Styrofoam blocks. This is a proven method of packing cases for shipment to avoid damage.
Antec provides several accessories with the One mid-tower case, and the most unique is the USB 3.0 to USB 2.0 adapter. If your motherboard does not have a USB 3.0 internal header, you can convert the front USB 3.0 cable to use a USB 2.0 header. This will obviously not provide you with USB 3.0 speeds, but it lets you use the front USB ports. In addition, they have included a feature manual (no installation instructions are included), tool-less hard drive rails, two cable ties, and the usual bag of screws.
