One of the decisions you will face when you purchase a new laptop computer is which case will best suit your needs. While there are many different cases on the market, many of the ones that are carried in the more popular department and office supply stores will not adequately do the job that is necessary to keep your computer safe. Each type of case has its advantages, but with an aluminum case you can avoid many of the disadvantages of the other.
Security - Cloth cases often times do make it possible to put a small padlock on the case; however this is just a small deterrent to a thief. It is easy to cut through the material and remove the computer from the bag. Plastic cases are more difficult to get through, but the plastic material can still be cracked to get to the computer. Aluminum cases offer a material that is much more difficult to get through. This makes it a less attractive target to most thieves. Instead of having to try to get through a metal case, they are more likely to move on to an easier target, leaving your computer safely in its place.
Exterior - When you consider the case you are going to purchase you need to look at the durability of the material the case is made from, and the ability of the case to protect what is inside. Plastic cases have a tendency to crack when they take a hard hit. When that happen the edges around the crack can become sharp and cause damage to people or other objects it comes in contact with. It also loses its ability to keep the moisture away from your computer.
Interior - The interior of a laptop case needs to be able to adequately hold the computer in place, and to provide enough padding to keep it protected. Most cloth cases offer at most a thin layer of padding, and possibly a couple of Velcro straps to secure the laptop. However, most of the hard sided laptop cases provide interior padding that is designed to keep the laptop securely in place. If the case is jostled your computer will still be safely in its place. This is important because even though the exterior of the case is not damaged; if the computer is allowed to bang around inside the case it will become damaged. The components inside the computer are fragile, and they will become damaged if the computer is jarred too much.
