Install stainless steel feet to the base of your Mac Pro with the Apple Mac Pro Feet Kit.
The standard Mac Pro does come with four feet already installed.
However, if you have purchased a Mac Pro with wheels, these are a great replacement for improved stability.
To install, it requires 4-mm (1/4-inch) hex bit, which is included but other tools are necessary.
By replacing the Mac Pro wheels, you will be reducing approx.
25 mm to the height of the frame.
