Buy A Computer Case

The case of the PC is a metal or plastic box designed to hold and protect the motherboard, the drives and the power supplies. Like motherboards and processors, cases come in many configurations, which are characterized by the orientation of the box, the number of drives and expansion slots it can hold, and the size of the expansion cards it can take.

The computer case should be durable, easy to service and have enough room for expansion.Make sure you buy a case which will fit into the space you intend to place it. This is where you decide between a desktop or a tower case. Make sure it has a power supply. Is the case clean?

Pay attention to the form factor: AT or ATX. Almost all newer motherboards are using the ATX form factor, so if you have an old case lying around, chances are a new board won't fit in it. If you do a lot of upgrading, you should get a case that is designed with this in mind, such as easily removed motherboard mounting plates, drive racks, etc. Things like the turbo switch and keylock are ancient technology. Try to have the buttons such as power and reset recessed, so that if you keep the case under the desk you won't accidentally kick the thing and reset it. Also, check the sturdiness of the case. Some cheaper cases are actually quite flimsy inside. Pay attention to how the case comes apart. Depending on the design, the screw less type is very user friendly. It's easier to work with a case that does not come apart in many pieces.

If you will be running a high-end processor in the case, pay attention to the cooling aspects of the box. Some carcases are come with case fans included, but your one don't have then you should make sure the case is designed to allow fan. You should have an unobstructed air hole in the front of the case for a front-mounted case fan, with some method of air flow from the rear of the case as well. Many power supplies also aid in cooling by having bottom-mounted fans that suck air from the inside of the case and blow it out the back through the power unit. And, along this line, pay attention to the wattage rating of the power supply included with the case. If you will be running either a large amount of hardware or fairly high-end hardware in this case, get a good strong power supply.

In many times power supply can make trouble to you. There is more chance to power supply burning up. If you can't tracked it down at right time, the whole PC can Gone and could not turn it on again.

As far as brands go, there are many good manufacturers out there .Many shops have very sturdy cases that are easy to work with that are unbranded. Many other brands can be just as good. I've even seen some good brand cases that are semi-translucent. If you want a futuristic look, these may interest you.

All aluminum cases are now started to catch on as have black ones. If you’re into modified cases, you can get them pre-modified with viewing holes and everything. Or, if you’re so inclined, you can grab a nice case and do your own mods to it. For some reason, though, I’ve never been keen on tearing huge holes into my PCs, but maybe it’s just me. I would advise you to keep away from the ones with plastic cases they are crap and fall apart unless kept in the cupboard and never taken out to add anything.

List and describe the factors in choosing the computer case?
  • Model type: Desktop (lays flat) versus tower (stands up)Size: Case should have enough space for installed components.
  • Available space: Desktop cases allow space conservation in tight spaces whereas tower can be located under desk.
  • Amount of devices: More devices need more power, which also requires a larger power supply.
  • Power supply: Must match the power rating and connection type.
  • Environment conditions: If you work in a dusty environment, you need to choose a case that
  • reduces the amount of dust that enters the system.
