A computer tower can come in a wide variety of shapes and sizes and can also be made from a wide range of materials including steel, plastic, aluminum and more. The size of a computer tower range from small mini-towers to medium sized mid-towers and all the way up to full-size towers, depending on what the computer is being used for and how powerful it is.
