Description

The present invention relates to a computer main body case for storing a hard disk device installed inside a computer in the computer main body.

2. Description of the Related Art In recent years, there has been a significant demand for miniaturization of a computer main body that stores a hard disk device installed in a computer with high performance. That is, downsizing of the computer main body contributes to space saving when a plurality of computers are installed side by side, and is an important factor in selecting a model.

On the other hand, when the computer main body is downsized, it is important to take measures against heat dissipation of the hard disk device stored in the computer main body. In other words, downsizing increases the factors that obstruct the air flow in the housing of the computer body. In particular, the computer body with the highest operational reliability is downsized with a structure that cannot guarantee heat dissipation in the housing. It is not possible.

In addition, for a computer, the mountability and expandability of peripheral devices are also important factors when selecting a model. In particular, expansion and replacement of hard disks has a problem that it takes time and labor to expand and replace because the side doors of the computer main body must be opened and wired. In order to solve the problem, a hard disk device as disclosed in Patent Document 1 has been proposed.
