Floor structure for the environment of a modular computer system

A modular and readily arrangeable raised floor structure for computer system sites is provided wherein the weight of the hardware units is supported by raised support members of rigid construction integrally formed with the hardware units and disposed on the permanent flooring in the site area, and the area between and surrounding the hardware units is rendered conveniently accessible to human attendants by modular raised floor panels of less rigid construction abuttably arranged relative to one another and to the raised support members of the hardware units, said raised support members integrally formed with the hardware units and said abuttably arranged raised floor panels serving to accommodate hidden interconnections of various types between the hardware units and to facilitate coupling of the system with external power and cooling sources.
