Different form. Same powerful factors.
Mac Pro is also available in a rack mount — with all the same performance features and configuration options as the tower — for spaces better suited to a rack design. The rack mount features the airflow‑maximizing 3D lattice and stainless steel handles on the front and tool‑less stainless steel slide rails in place of feet or optional wheels.
The rack is a $500 premium over the Mac Pro’s regular casing; however, it’s a much better form factor if you’re planning to install the computer in a data center or cabinet.
