Title: Framework configueuration of a computer host

Description:
FIELD OF THE INVENTION  
      The present invention relates generally to a framework configuration of a computer host. More particularly, the present invention relates to a framework configuration of a computer host that has an external power supply installed outside a computer host for saving volume, and the CPU of the motherboard is positioned far from the user so as to flexibly configure the storage device of the computer.  
     BACKGROUND OF THE INVENTION  
      Generally, the framework configuration of a computer host of the prior art, it&#39;s power supply is installed inside the housing of the computer host, and then the motherboard, Floppy Disk Drive, Hard Disk Drive and an Optical Drive are installed inside the housing respectively. However, the framework configuration of a computer host of the prior art cannot reduce the size of the housing, and the noise also cannot be reduced while the computer is running.  
      For example, Taiwan issued Patent No. 543501 “A FRAMEWORK OF A COMPUTER HOST” provides a framework of a computer host, which comprises: a small case, having at least one push exit opening and a plurality of opening; a motherboard, positioned inside the small case, for connecting a first connector of an Optical Drive; an interfacing Print Circuit Board (PCB), stacked above the motherboard, a Hard Disk Drive could be positioned on the rear side of the interfacing PCB, and an Optical Drive could be positioned on the front side of the interfacing PCB; a holder, positioned between the interfacing PCB and the Optical Drive, for connecting the Hard Disk Drive to the Optical Drive. The prior art uses an interfacing PCB that respectively has a Hard Disk Drive and the Optical Drive connector to save the wiring space of the computer housing. However, the interfacing PCB is consisted of a PCB and the circuit layout and size of the PCB is determined when it is designed. If changing the size of the computer housing, the appearance of the interfacing PCB may be could not match the requirement of the computer housing and it must be designed again. Thus the cost will be increased. Furthermore, if the interfacing PCB failed, the user must buy another interfacing PCB to replace, thus also increasing the user&#39;s loading.  
      Therefore, it needs a framework configuration of a computer host for the purpose of matching the requirement of light, thin, short and small of the mini computer.  
     SUMMARY OF THE INVENTION  
      To solve the above problems, it is an object of the present invention to provide a framework configuration of a computer host, which has an external power supply installed outside a computer host for saving volume, and the CPU of the motherboard is positioned far from the user so as to flexibly configure the storage device of the computer.  
      To accomplish the above object of the present invention, there is provided a framework configuration of a computer host, which comprises: a mainframe, having a bottom plate on it&#39;s bottom portion; a motherboard, positioned above the bottom plate of the mainframe, having at least a CPU slot and a power input outlet thereon; a storage device holder, stacked over a space that is above the motherboard for positioning a storage device; and a cover, for covering over the mainframe.  
      The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Referring to  FIG. 1  shows an appearance of a framework configuration of a computer host in accordance with one embodiment of the present invention. As shown in  FIG. 1 , the framework configuration of a computer host comprises: a mainframe  1 ; a motherboard  2 ; a storage device holder  3  and a cover  4 .  
      Wherein, the mainframe  1 , having a bottom plate  11  on it&#39;s bottom portion; the motherboard  2 , is positioned above the bottom plate  11  of the mainframe  1 , having at least a CPU slot  21  and a power input outlet  22  thereon, wherein, the power input outlet  22  is for example but not limited to a 3×2 outlet, for providing a plug of an external power supply (not shown) plugged into. The CPU slot  21  is positioned behind the motherboard  1 , namely, far from a user for the purpose of avoiding that the heat source (for example but not limited to a CPU, Hard Disk Drive or an Optical Drive) concentrates at the front half side of the motherboard  2  so as to flexibly configure the storage device of the computer, besides, the heat generated by the CPU can be exhausted outward directly by the fan (not shown) positioned behind the mainframe  1  so as to improve the heat dissipating efficiency.  
      The storage device holder  3 , stacked over a space that is above the motherboard  2  for positioning a storage device, it further comprises a fixing holder  31  and a moving holder  32 . Wherein, the fixing holder  31  is used to hold a Floppy Disk Drive  311  and an Optical Drive  312  and the Optical Drive  312  is stacked over the Floppy Disk Drive  311 ; the moving holder  312  is used to hold a first Hard Disk Drive  321 . The cover  4  is used to cover over the mainframe  1 , whereby, after the cover  4  covering over the mainframe  1 , a plug of the external power supply (not shown) can be plugged into the power input outlet  22  for operating.  
      Referring to  FIG. 2  shows a detail configuration of the moving holder  32  in accordance with one embodiment of the present invention. As shown in  FIG. 2 , the fixing holder  31  is used to hold a Floppy Disk Drive  311  and an Optical Drive  312 , besides, the fixing holder  31  also can be positioned a second Hard Disk Drive  313  and an Optical Drive  312 , and the Optical Drive  312  is stacked over the second Hard Disk Drive  313 .  
      Referring to  FIG. 3  shows a diagram of disassembling the fixing holder  31  and the moving holder  32  in accordance with one embodiment of the present invention. As shown in  FIG. 3 , the fixing holder  31  of the present invention further comprises at least one sliding slot  314 , and has at lease one fastener  322  positioned at a place that is top of the moving holder  32  and opposition to the sliding slot  314  and can slide inside the sliding slot  314 , whereby, the moving holder  32  can remove from the fixing holder  31  so as to conveniently assemble and disassemble the first Hard Disk Drive  321 .  
      While the invention has been described with reference to a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
