One of my friends turned me onto this really great modder in my area Totally Lame Robot. She mods all things from collectibles, consoles and controllers to better them and make them look awesome. One thing that really caught my eye was the modding of an Xbox 360 so it has a custom MW3 case.
The bulk of the case looks like the poster which is simply bad ass. She has even modded the faceplate to match. Check out the video below that shows off the case mod and the following video that shows how she did it. Feel free to comment what you think and be sure to check out her other videos on her TotallyLameRobot Youtube Page.
