Many unofficial custom cases can be purchased from independent manufacturers and are available in a wide range of colors and styles. The original outer casing of the console may be removed using special tools often provided with custom cases but also sold separately, allowing said case to be fitted. Custom cases are generally based on moulds of official cases but with all Microsoft branding removed. As such, they do not change the size or shape of the console, only the aesthetics. Custom cases are not endorsed by Microsoft, and removing the official case will void any warranty on the console.
