A system and method for planning and configuring the components of a modular computing system is provided. In some embodiments, the method for planning an implementation of a modular computing system comprises presenting a user interface at a display device, the user interface including a plurality of user-selectable objects, each of the user-selectable objects representing a component of the modular computing system. A user selection is received via a user input device. The user selection is from among the user-selectable objects and specifies one of an enclosure, an existing component, and a future component of the modular computing system. A representation of the specified one of an enclosure, an existing component, and a future component is displayed at a display device. The user selection is verified with respect to an implementation guideline. An indicator of whether the user selection meets the implementation guideline is displayed at the display device.
