What are the advantage of different computer casings?

Answer 1

The main differences between cases are: * size * cooling * mounting space/style The size of the case (see: form factor) is very important, as certain motherboards won't fit in smaller cases. Also, with the huge video cards that are entering the market, some cases may not have enough room to fit your video card along with your other hardware. Different cases have different capacities for cooling, determined mostly by ventilation and fan size/placement. Certain other factors such as the locations of internal walls and mounting apparatus can affect the ability of a case to dissipate its heat. A good case will keep the parts cooler than they would be if they were sitting in the open, due to good air flow. Finally, most computers use a number of internal drives, such as a DVD-RW or a hard disk. You have to have some way to mount these drives inside the case. Older cases used screws, but more modern cases incorporate snapping parts and sliding rails. The design of the mounting platforms can make installing/removing hardware very hard or very easy.
