The first box is the exterior accessory pack 16 and case 18. The box contains an interior suspension system that protects the computer unit. The suspension system minimizes gravitational (G) forces to the computer unit if the box is dropped. Ideally, the suspension system will protect the box from up to 100 G's if dropped. In this embodiment, the box is made of light weight aluminum that is lined on the interior with a 0.5 inch thick layer of polyurethane foam. This layer of polyurethane serves to isolate and cushion the interior box against the force and velocity of an impact. The interior box is the computer unit itself. The thickness of the foam may vary in other embodiments according the material composition of the polyurethane and the level of protection needed by the user. 0040 FIGS. 11 through 14 show the procedure for removing the interior box. First, as shown in FIG. 11, the bezel 42 is held in place by several screws 40. Once the screws 40 are removed, the bezel 42 is removed as shown in FIG. 12. Next, the interior box or computer unit 44 is pulled out of the protective case 18 as shown in FIGS. 13 and 14. The flexibility of being able to remove the interior computer unit 44 allows for ease of maintenance and upgrade of the computer. Additionally, the computer unit 44 is rack mountable after it is removed from the protective case 18 with a separate adapter kit. 0041 Other embodiments of the present invention include a portable computer with a triple panel display screen. FIGS. 15A through 15C show a packed up computer 10 with a triple display screen 46 that is folded. The computer 10 is packed up and unpacked in a similar manner as previously described in FIGS. 1 through 6. However, the folded triple display screen 46 will require additional internal space. This may result in 2.5 inches being added to the width of the computer case in some embodiments. FIG. 16 shows the computer set up with the triple display screen panels 46 fully extended. 0042 Other embodiments of the invention include the portable computer configured to act as a portable network server. Additionally, the invention could include a portable computer configured with multiple microprocessors or an SCSI (small computer system interface) array of up to eight SCSI drives. The advantages of the present invention include having a portable computer that is capable of high end workstation performance. The computers could be used for such demanding applications as: CAD (computer aided drafting); video editing; animation; and other graphics intensive applications. Also, the portable computer is ideal for setting up local area networks for such applications as graphics intensive, high performance computer games with multiple networked players. 0043

FIG. 18b shows the computer 44 with the bezel 42 in place and the air flow 50 exiting out of the dual air channels 51. In this embodiment, the air flow 50 exits the computer in the direction of the user so that the thermal cooling system may be used as a hand warmer for the user. 0044 Some embodiments of the present invention include special supports for PCI cards that are installed in the computer. A PCI (Peripheral Component Interconnect) card is a card that is installed in the computer in certain specified internal connecting sockets. The card contains interface circuitry for external components that may be used with the computer. PCI refers an industry standard specification for the cards that is known to those of ordinary skill in the art. Typically, computers contain multiple sockets that allow for the installation of more than one PCI card at a time. FIG. 19 shows a view of the internal arrangement of the computer 44 with an exploded view of the PCI card retainer support plate 54. The computer 44 contains PCI card(s) 52 that are located in a corner of the computer adjacent to the top wall of the unit and the I/O bank 30. In this embodiment, the retainer support plate 54 is a removable plate that is attached to an opening in the top of the computer 44 with multiple screws 58. The support 54 has two separate cushions 56 to support the PCI card(s) 52. As shown in FIG. 20, each cushion 56 has a notch 60 that holds its PCI card 52. In this embodiment, the cushions are made of a polyurethane material. The cushions serve to hold the PCI cards in place and prevent disconnection from the connecting sockets during a drop or sudden impact to the computer. In other embodiments, the number, size, shape, and material composition of the cushions may vary according to the internal arrangement and configuration of the PCI cards for the computer. 0045 In summary, the present invention allows for a high performance workstation computer to be portable without any performance limitations. Such advantages include: a tilting mechanism that allows for an ergonomically comfortable screen orientation; a box in box construction that protects the interior computer unit from shocks of sudden impacts; storage of accessories in a convenient accessory pack for the computer; an interior computer box that can be easily removed from its protective case and rack mounted; a triple display screen configuration for the portable computer; a thermal cooling system; and a retainer support plate for PCI cards. 0046 While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed here. Accordingly, the scope of the invention should be limited only by the attached claims.
