Apple Mac Pro Wheels Kit
 
Put your Mac Pro on wheels with the Mac Pro Wheels Kit. The custom-designed stainless steel and rubber wheels make it easy to move your Mac Pro around, whether sliding it out from under your desk or across your studio.
Installation required. A 1/4-inch to 4 mm hex bit is included, but additional tools are necessary. Replacing the Mac Pro feet with wheels adds approximately one inch to the height of the frame.
