1. A computer housing assembly, the improvement comprising:

  • a mainframe housing unit consisting of rectangular base having upstanding, opposed side walls, an upstanding rear wall and a rectangular cover plate having edges adapted to rest on said walls, first releasable fastening means carried by the upper portions of said side and rear walls and the corresponding edge portions of said plate connecting said cover plate to said base;

    a front panel forming the upstanding front wall of said unit, second releasable fastening means connecting said panel and said base and side walls, said front panel having a left side recess and lid therefor, a center slot opening for receiving a disk drive and a right opening for receiving a disk drive housing, said panel having opposed channels on the upper and lower surfaces and left and right covers slidably mounted therein for covering the left recess and lid and right opening;

    a rectangular disk drive housing slidably received in said unit through the right opening in said front panel, said housing having upper, lower, back and side walls, said side walls having a plurality of aligned mutually spaced holes and retaining clips mounted adjacent thereto, said right opening defining channels at the sides thereof and mutually spaced rails mounted on the sides of said housing and being slidably retained in said channels, a supporting track mounted within said unit and a block mounted on said housing and slidably received in said supporting track, L-shaped fastening rods extending through the holes in the side walls for threadedly engaging a disk drive, the legs of said rods being retained in the clips mounted adjacent the holes;

    a power supply holder including a L-shaped support platform mounted within the mainframe housing with a leg of said platform resting on said base and a stop plate mounted on the platform a predetermined distance from a vertical wall of said mainframe housing so that a power supply unit can be supported on said platform between said stop plate and wall;

    an interface card fastening housing, the upstanding rear wall of said mainframe unit forming a plurality of vertically directed slots, said interface card housing being mounted within the unit registered on the slots, said housing having a vertical support disposed on each side of each slot, a plurality of unitary clamps mounted above said slots and a plurality of fastening plates mounted on each pair of adjacent supports to retain interface cards in said slots; and

    mother board fastening housing having an elongated frame mounted within said unit with a plurality opf mutually spaced vertical tubes extending therethrough, each tube having two eccentric flanges disposed around the bottom end thereof and a plurality of fastening element having an expanded head and an elogated body extending through each tube so that when a mother board is mounted on said housing tubes will extend through holes therin with the head of said fastening elements retaining said booard thereon, each element further having a biased, split cone at the end thereof extending from the bottom of each tube said cone normally having a diameter greater than that of the tube and being disposed between said flanges so that rotation thereof will compress said cone between said flanges so that said element can be withdrawn through said tube.
