Opening and closing lids for opening and closing portions on the facing casing are provided as the top panel 16 and the bottom panel 17. For example, slide protrusions are provided on the edges of the top panel 16 and the bottom panel 17, respectively. On the other hand, the slide protrusions are engaged with the upper and lower edges of the main body portion of the casing 8, respectively. In this state, for example, a slide groove that can be mounted while sliding the top panel 16 and the bottom panel 17 is provided. Thereby, the top panel 16 and the bottom panel 17 are detachably attached to the upper part and the bottom part of the main body portion of the casing 8 without using a tool such as a driver, for example.

  As shown in FIG. 2, the CPU 15 and the main memory 14 are attached to and detached from the lower surface of the processor board 12 (the board surface in the bottom side direction of the casing 8) via a dedicated memory socket 14a or a CPU socket (not shown). It is installed freely. The processor unit 6 is provided with a so-called chip set including a north bridge 18 and a south bridge 19 mounted on the processor board 12. In the present embodiment, an example in which the north bridge 18 and the south bridge 19 are mounted on the upper surface of the processor board 12 (the substrate surface in the upper direction of the casing 8) is shown. May be implemented.

  The riser unit 7 includes a riser board 20 as a second control board, a plurality of expansion connectors 21 and I / O (Input / Output) port groups as second electronic components mounted on the riser board 20. 22. The riser board 20 is disposed in a vertical position so as to be orthogonal to the processor board 12. Specifically, as shown in FIG. 4, the riser board 20 extends in the depth direction of the casing 8 from the center of its one surface (the surface of the left side [surface opposite to the right side direction in the figure]). The connector 23 provided in this manner is attached to the terminal portion 24 provided at the right edge (the edge portion of the board) of the processor board 12. As a result, the processor board 12 and the riser board 20 are arranged in a T-shaped cross section, and the one riser board 20 is fixed in a state of being moved toward the right side (right side in the figure) in the casing 8. ing.

  The I / O port group 22 is an interface for inputting / outputting data for controlling various devices. As shown in FIG. 2, the rear edge (the edge portion of the board) of the riser board 20 is provided. Is arranged. That is, the I / O port group 22 is fixed to the back surface of the casing 8 in such a manner that each terminal portion is exposed to the outside from the rear side of the casing 8. Examples of the I / O port group 22 include a serial port, a parallel port, a PS2 port, a VGA (Video Graphics Array) port, a USB (Universal Serial Bus) port, and the like.

  Further, the plurality of expansion connectors 21 are, for example, interfaces for PCI (Peripheral Component Interconnect), and a connector 23 for connecting the processor board 12 on the riser board 20 is mounted as shown in FIG. Each is mounted in parallel with the board surface. That is, an expansion board 25 such as a SCSI (Small Computer System Interface) card, for example, disposed opposite to the upper surface of the processor board 12 is attached to the expansion connector 21 via the terminal portion 34 (two). Yes. Note that the expansion board 25 attached to the second-stage expansion connector 21 from the top is not shown in FIG. A metal plate portion for holding an output terminal or the like is provided at the rear edge of the expansion board 25, and this plate portion is screwed to the back surface of the casing 8. As a result, the processor board 12, the riser board 20, and the expansion board 25 are arranged in a U-shaped cross section.

  Further, in this embodiment, although the expansion connector 21a is also provided at the portion where the expansion board 25 can be mounted so as to be opposed to the lower surface of the processor board 12, the expansion of the CPU 15 and the main memory 14 and the replacement of parts are performed. Therefore, the expansion board 25 is not attached to a position facing the lower surface of the processor board 12. Further, the PCI card applied as the expansion board 25 is a so-called half-type PCI card in which the metal plate portion screwed to the back surface of the casing 8 is short in consideration of downsizing of the server body. Here, such an expansion board 25 may be, for example, an expansion board on which the above-described I / O port is mounted.

Next, the component layout of such a server 1 will be described in detail.
That is, as shown in FIGS. 1 and 2, the external storage device such as the hard disk 3 and the CD drive 5 and the PC card slot 9 are arranged close to the front side in the casing 8. Further, the processor unit 6, the riser unit 7, and the expansion board 25 attached to the riser unit 7 are arranged on the rear side in the casing 8 so as to avoid these drive devices and the PC card slot 9 in the depth direction in the casing 8. It is arranged close to. The power source 2 is fixed to the back surface of the casing 8 such that its own power fan (not shown) is exposed. Specifically, the power source 2 is arranged on the upper surface side of the processor board 12 and further arranged so as to approach the left side in the casing 8 so as to avoid the expansion board 25 in the width direction in the casing 8. Further, as described above, the CPU 15 and the main memory 14 are disposed on the bottom side of the processor board 12.

  Therefore, in the server 1 including the casing 8 according to the present embodiment, the main control board on which the main components of the apparatus main body are mounted is divided into two parts of the processor board 12 and the riser board 20, and the casing 8 The power supply 2 and the expansion board 25 are arranged on the upper side, and the CPU 15 and the main memory 14 are arranged on the bottom side, with the processor board 12 mounted with the riser board 20 being orthogonal to each other. Thereby, according to the server 1, the space in the casing 8 can be used efficiently and the apparatus main body can be reduced in size. Further, according to the server 1, an air blowing path for cooling the CPU 15 by the fan 10 is formed between the bottom surface of the processor board 12 and the inner wall surface below the casing 8 (the left and right sides below the casing and the inner surface of the bottom portion). Since it is substantially constituted, a cooling action can be given to the CPU 15 without providing a special duct structure. Thereby, for example, the manufacturing cost of the server 1 can be reduced.

  Further, in the server 1 of the present embodiment, as shown in FIGS. 2 and 3, by removing the top panel 16 and the bottom panel 17 from the casing 8, the upper portion of the casing 8 facing each surface of the processor board 12 and The bottom can be easily opened to the outside. Thus, according to the server 1, the expansion board 25, the CPU 15, the main memory 14, the hard disk 3, and the CD drive 5 in the casing 8 can be accessed from both sides of the processor board 12 (parts can be attached and detached). Therefore, when adding or replacing internal components, the addition or replacement can be easily performed without performing extra work such as removing a non-target component (for example, the power supply 2).

  Here, in the server 1 of the present embodiment, as shown in FIG. 3, the protective panel 26 as an inner lid is also provided on the inside of the casing 8 after the top panel 16 and the bottom panel 17 as outer lids are removed from the casing 8. It is detachably attached to the main body. In other words, the casing 8 has a double nesting structure including the first access hole (component operation hole) 32 on the outside and the second access hole (component operation hole) 33 on the inner side. Yes. The protective panel 26 is an inner lid for closing the second access hole 33. More specifically, the protection panel 26 requires a certain level of technical knowledge, and the operation frequency is relatively low. For example, operations such as a dip switch and a jumper switch for setting an operation clock of the CPU are performed. The restriction part 27 is covered. Thereby, it can suppress that the user of the server 1 performs incorrect setting operation.
