ABSTRACT:
A computer main frame includes a bottom block connected with an upper cover through tongue-and-groove joint, for positioning therein of floppy disc and hard disc. The upper cover includes an inner wall surface specially designed to conform to the geometry of the floppy disc and hard disc being received. The floppy and hard disc which are received in the main frame have holes thereon for insertion therein of stub tenons upstanding from the bottom block, such that the positioning of the floppy and hard disc can be secured without the use of any fastening means.
