Housing of data processing system with mechanism for easy removal and insertion of disk drive

A housing of a data processing system with a mechanism for easy removal and insertion of a disk drive, comprising:

• a shell having two opposite side walls, each with a sliding rail;
• two opposite guiding plates slidable on the sliding rails, a front section of each guiding plate having at least one guiding pin;
• a rear plate for carrying at least one rear disk drive, two opposite sides of the rear plate being fixed on rear sections of the guiding plates, the rear plate being capable of moving relatively to the shell through the cooperation of the guiding plates and the sliding rails;
• a front plate for carrying at least one front disk drive, each of two opposite sides of the front plate having at least one step-shaped guiding groove, the guiding groove having a first level and a second level, the guiding pins of the guiding plates being slidable in the guiding grooves of the front plates;
• wherein, when the front plate is in a first position where the guiding pins are in the second level of the guiding grooves, the front plate is jointed with the rear plate;
• and when the front plate is in a second position where the guiding pins are in the first level of the guiding grooves, the front plate is stepped away from the rear plate so that the front and rear disk drives are both exposed for easy removal and insertion.
