NZXT packs the Source 530 into a brown cardboard box. The front holds an image of the chassis itself, while the rear details all of its major features. You will also find an image of the front on one of two sides; the other lists the chassis' specifications. Two carrying holes should help you take the package home from the post office.
Two fairly sturdy Styrofoam spacers hold the chassis in place and protect it from falling damage, and a plastic bag has been applied to shield it against fingerprints and scratches.
NZXT also includes various black screws to assemble the system. Each type has neatly been put into individual plastic bags. You even get a ton of zip ties to keep everything tidy within your system. A manual and a promotional pamphlet round out the chassis' extras.
