Xigmatek ships the Asgard 381 chassis in a basic brown box with black print. Considering that the chassis is geared toward SI projects, this is more than adequate. You will find an image of the chassis on the front, while a blow-up diagram takes most of the space on the rear. Two more views of the case can be found on either side of the box.
Fairly compact Styrofoam spacers hold the case in place, while a clear plastic bag is used to protect it from fingerprints and scratches.
You will not get a lot of extras with the Asgard 381, but there is still enough to build a full system. This includes screws, a 3.5" cover to be used in one of the 5.25" bays, and a basic manual.
