Rocks. Chances are everyone has thrown a rock at least once. When I think of a rock, the adjectives, strong, stable, and heavy, come to mind. Cooler Master's ROC is no different, and it is highly likely that the name ROC is inspired by real rocks. While ROC is strong, stable and heavy, it is not something you throw. ROC is a stand for Apple's highly stylized MacBook Pro and iPad devices.
