I'm going to go ahead and call this the front just because of the large rendering of a sports car on here that somewhat resembles a Mustang. On the fender you will also see the GT1 naming of this InWin chassis.
Spinning to the right one panel you now see that this plain brown box with two color printing incorporates the specifications chart on this side.
What is more likely intended as the front panel of this box is the side that gives you a look at the front I/O panel, has the large name at the top, and offers the eight features at the right to be found in the GT1.
The last panel holds some important information as well. Here you get check boxes for both the color of the chassis as well as the type of side panel. Here we have a white chassis with the side panel window. Taking the majority of this panel is the list of 11 features they covered this time.
If you open the box from the top, you will find the hardware and accessory bag that used to be taped into place here. It must have had a hard journey as not only the main bag was flopping lose in here, but the bags inside were also spilling their contents.
Protecting the GT1 on this same journey, InWin used Styrofoam for the top and bottom supports, wraps the chassis in a plastic liner, and protects the side window with a layer of plastic stuck to the outside of it. All of this worked very well and the chassis arrived in perfect condition.
