Case modification, commonly referred to as case modding, is the modification of a computer case or a video game console chassis. Modifying a computer case in any non-standard way is considered a case mod. Modding is done, particularly by hardware enthusiasts, to show off a computer's apparent power by showing off the internal hardware, and also to make it look aesthetically pleasing to the owner.
Cases may also be modified to improve a computer's performance; this is usually associated with cooling and involves changes to components as well as the case.
