The i5 ships in a plain brown cardboard box that is quite generic. There is no image of the chassis itself, just a big X2 logo on both larger sides of the box. The smaller sides let you know what chassis is in there by listing the item number and not the actual model, which makes it rather difficult for you (or any distributor) to quickly identify the right package.
The i5 is held in place by two standard Styrofoam spacers and is protected from fingerprints and light scratches by a clear plastic bag.
You will also find a basic manual and a set of black screws inside the box. While there are some long screws to allow you to install radiators with fans, X2 has included too few should you want to fill the chassis with all the components possible.
