The Metal Art CPU Caddy uses modern design and innovation to help your computer fit into your life. Both in function and in form. Forged from steel, it puts your CPU up on wheels so you can roll it around a little without any lifting. The more digital our lifestyle gets, the more we need to plug and unplug things from the computer. The CPU Caddy makes interaction between your computer, digital camera, MP3 player, joystick, PDA and printer a little easier.
