If you balked at the $400 extra to configure a Mac Pro with wheels (let alone the $699 to buy the kit after the fact), OWC is coming to your rescue. The company is taking pre-orders (via MacRumors and The Verge) for a Rover Pro wheel kit that will normally cost $250, and are available in advanced for $199. You could save enough money over the Apple solution to get a (modest) RAM or video card upgrade for the machine itself.

Importantly, you don’t have to give up the Mac Pro’s default feet like you do with the official wheels. The Rover Pro kit attaches to the feet with a “few hand twists,” OWC said. And did we mention there are included wheel stops, so your premium workstation won’t roll away on its own?
