a mainframe comprising a casing made from extruded aluminum and mounted in said back opening of said hollow frame, said casing comprising a front wall abutted against said hollow frame around said front opening, a recessed accommodation chamber located in said front wall and a plurality of engaging members located at two opposite locations in a top side in said recessed accommodation chamber, each said engaging member comprising a stepped hook portion slidably engageable into the retaining groove of one respective said retaining member of said display device, a motherboard mounted in said recessed accommodation chamber, said motherboard comprising at least one heat-emitting source abutted against an inner surface of said casing for quick dissipation of heat, a mating connector unit located at a top side of said motherboard, said mating connector unit comprising a second electric connector casing slidably detachably connectable to said first electric connector of said connector unit of said display device.

2. The cooling structure integrated all-in-one computer as claimed in claim 1 , wherein said display device further comprises a control module for controlling display settings, said control module comprising a circuit board mounted in one lateral side in said back opening of said hollow frame and electrically coupled with said connector unit.

3. The cooling structure integrated all-in-one computer as claimed in claim 1 , wherein each said engaging member of said mainframe comprises a base portion formed integral with one end of the respective said stepped hook portion and affixed to said front wall of said casing.

4. The cooling structure integrated all-in-one computer as claimed in claim 1 , wherein each said engaging member comprises a base portion affixed to said front wall of said casing, the respective said stepped hook portion upwardly extended from said base portion, and a plurality of rails longitudinally located on said front wall of said casing.

5. The cooling structure integrated all-in-one computer as claimed in claim 1 , wherein said casing of said mainframe casing further comprises a plurality of heat-transferring bearing block located in said recessed accommodation chamber and abutted against said at least one heat-emitting source of said motherboard to form a heat transfer path.

6. The cooling structure integrated all-in-one computer as claimed in claim 5 , wherein said mainframe further comprises a heat sink set between said motherboard and said casing, said heat sink having two opposite surfaces thereof respectively abutted against said at least one heat-emitting source and said heat-transferring bearing blocks, said heat sink comprising a plurality of heat pipes, said heat pipes being extended out of said heat sink and bonded to an inner wall of said casing.

7. The cooling structure integrated all-in-one computer as claimed in claim 5 , wherein said casing further comprises a plurality of internally threaded columns located in said recessed accommodation chamber around said heat-transferring bearing blocks for the fixation of said motherboard with screws.

8. The cooling structure integrated all-in-one computer as claimed in claim 1 , wherein said casing of said mainframe casing further comprises two side panels located at two opposite sides of said recessed accommodation chamber, each said side panel comprising a plurality of through holes, a transverse slot located in a bottom side of said recessed accommodation chamber, and a back plate mounted in said transverse slot, said back plate comprising a vertical mounting wall affixed to said casing by screws and a plurality of pierced holes arranged in a line; said motherboard further comprises a plurality of ports respectively located in said pierces holes of said back plate.

9. The cooling structure integrated all-in-one computer as claimed in claim 8 , wherein said casing further comprises a finger plate located at a bottom side of said transverse slot on the middle, and an outer cover detachably fastened to said transverse slot to cover said back plate.

10. The cooling structure integrated all-in-one computer as claimed in claim 1 , wherein said mainframe further comprising a first shaft member backwardly extended from said casing, a base, a second shaft member upwardly extended from said base, a support arm having opposing top and bottom ends, a first hinge member connected between said first shaft member and the top end of said support arm, and a second hinge member connected between said second shaft member and the bottom end of said support arm.
