Before You Buy Personal Computer Cases

The computer case is the most visible aspect of a computer system and dictates much about how and what will make up a personal computer. Choices for a personal computer enclosure have changed dramatically over the years. The standard beige desktop design has long since gone. Now consumers can chose from a variety of materials, sizes, shapes and colors. This guide helps point out some of the key things to consider when selecting a case for your next desktop PC.

Form Factor

The majority of desktop computer cases sold on the market now are tower cases. These vertical cases can range in size from the mini all the way up to full tower. All of them will fit the average desktop components, the real difference being the amount of space available for components and working inside of it. Small form factor cases generally are much smaller in size but require specific hardware, so always make sure you are aware of such limitations before buying. Home theater gear is design more like traditional desktop cases but styled to reside with other stereo components.

Construction

The material and the quality of the workmanship can make a huge difference in a case. Mose cases at their base are either made with steel or aluminum. Plastics and acrylics may also be used to supplement the design and look of the case. These materials can impact how heat is held in or distributed out of the system as well as how heavy or portable it may be. Be sure to check how the case is put together. Beveled or finished edges can reduce the risk of cuts while working inside of the case. Hinges for doors should be sturdy to prevent breakage.

Power Supplies

Most computer cases these days are sold independently from the power supply. Still, some cases do come with a power supply included. If one does come installed in the case already, be sure to verify that its wattage will meet the requirements of the components that will be installed inside of it. In addition, check to make sure it has the appropriate connectors and sufficient number of cables for all of the internal components. Finally, other aesthetic features such as fans and noise might also be important to consider.

Layout

The way that a case is designed can directly impact its usage. How the fans and ports are situated on the computer can improve access or increase the style of the case. For example, if a case will be on the floor, then extra USB, audio and FireWire ports on the top of the case would be better than the front. Conversely, the ports would be better on the front if the case is inside a cabinet or on the top of a desk. Drives behind a door panel can reduce noise and give the case a more uniform look, but also make them more difficult to access.

Cooling

Heat can directly impact the performance of internal desktop components. Because of this, cooling is an important thing to think about. The various vents, fans and ducts that can be built into a case can either aid or deter the flow of heat from the interior to the exterior of the case. Then again, having a case with a large amount of airflow can also lead to a large amount of dust buildup inside of the case. Filters and screens to help reduce the dust can be helpful.

Accessories

Modding used to be a popular hobby for many enthusiasts. Today, many case manufacturers offer accessories to help personalize cases on the market. These can be simple items such as a case cover with a built-in window to specialized
