The Kraken X40 is supplied in a very similarly designed box to the X60, which features a large image of the cooler on the front. The black and white colour scheme reflects that used for the cooler's fans.
Turning the box around reveals further images of the cooler alongside some details of the key features and specifications of the unit. The packaging is fairly substantial and should be able to withstand a torment of abuse from negligent couriers.
There are a number of accessories included within the box, most of which relate to the rather complicated mounting mechanism that ensures compatibility with all major sockets. There is also a software CD and installation guide included.
