Abstract
Abstract A data processing apparatus comprising a disk unit, a power supply unit, at least one printed circuit board, a heat-exhaust fan, and a box accommodating the disk unit, the power supply unit, the printed circuit board, the heat-exhaust fan. Both the depth and height of the box are larger than the width and has first and second side surfaces defined by the depth and height, bottom and top surfaces defined by the depth and width, and front and rear surfaces defined the height and width. The disk unit and the power supply unit are disposed adjacent to the first side surface. The printed circuit board is disposed adjacent to the second side surface. The disk unit is disposed on the front surface, and the power supply unit is disposed on the rear surface. The apparatus is supported by a first leg and a second leg. Cooling air is exhausted through the first leg which includes a cut-out which communicates with a hollow portion. The second leg includes two non-aligned ends which extend beyond the sides of the apparatus and allow two of the apparatuses to be placed side by side.
