Apple has debuted a Mac Pro Wheels kit for the Mac Pro. The $699 kit’s custom-designed stainless steel and rubber wheels are designed to make it easy to move your Mac Pro around.
Installation is 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.
Apple has also announced a Mac Pro Feet Kit. You can use the $299 kit to install stainless steel feet to the bottom of a Mac Pro. The standard Mac Pro comes with four feet already installed, but if you purchased one with wheels, you can replace each of them with feet for improved stability.
Again, installation is required. A 1/4-inch to 4 mm hex bit is included, but additional tools are necessary. Replacing the Mac Pro wheels with feet reduces approximately one inch to the height of the frame.
