Thermaltake ships the Tower 100 in a full-color cardboard box with their signature design of an image of the chassis on two opposing sides. You will also find a specification table and another image on the rest of the box.
Two thick Styrofoam spacers hold the case in place and protect it during shipping, and a plastic bag is meant to keep fingerprints away during handling at the factory.
You will find several zip ties, a bag of black screws, and a little speaker. Thermaltake has also included two plastic plates meant to close the gap on the bottom shroud when using a short GPU. A manual rounds out the accessories which ship with the Tower 100.
