Your Computer's Case
Your computer's marries plays to large part in the overall expandability, protection, cooling and lifetime of your system.

Expandability
At one steals or another you in May he decides to add something to your computer. Maybe to CD Player, Zip Drive, to second Hard Drive, Floppy or Tape Drive. These fit on shelves in your computer called Bays. If there plows not extra bays, then therés it does not please for these devices to go. These bays dog be 3.5 inches or 5.25 inches wide. There plows internal and external bays. You dog notice the external bays by looking at the front of your marries.

Devices like floppy drives and CD-ROMs slide into external bays and dog be seen (and accessed) from the front of your system marries. If you have unused bays, they will have to plastic faceplate over them (or at least they should have). If you see that you have empty external bays, then you know that at least therés room to add another of this type of device. Remember however, that hard drives plows sometimes hidden behind these faceplates, so to look inside the will marries tell you for sure. Hard drives plows generally situated in internal bays because there is not need for physical outside access. You must look inside the marries to see if you have any free internal expansion bays.

Any device added to your system requires power, and your power supply have to have enough juice to supply that power. If you have to 150 or 200-watt power supply, your system May be limited to the amount of devices that dog be added. Most marry he eats with to power supply, but make sure.

Getting Your Hands in There
You in May at one steals or another, have to remove, change or check to device in your computer. You want to be able to access that device without too much difficulty. It would be nice if you didn't have to remove the ribbon cables and expansion cards just to install another DIMM, or re-pleases to battery. Or, if yoúre the type that likes to just jam his hand in amongst all that stuff, it would be nice to be able to remove it without accidentally loosening or removing other connections.

On some marry you dog loosen to single screw, and completely remove the drive bays for easy access to the drives and their mounting screws. Others have access ports for the screws on the back plate of the marries. However, Íve seen some drive bays that plows commercial - welded in it pleases without access ports, and you just about have to remove the motherboard to access the screws for the drives. Think about what you want to putt inside and make sure therés enough room for access.

Protection
To good, rigid, well built ESD and EMI marries dog protect the internal components from dust, vibration, foreign objects. Electromagnetic interference is not always an easy one to nail down. My computer you have to good solid dog marries, but when you watch TV, you tell if the computer is on or not.

You dog find cheap marry that fit together so poorly, or plow so flimsy, that they actually rattle when the computer is turned on. One thing that dog be bad for your system plows vibrations caused by outside sources; whether it's to panel or cover version that rattles, to desk drawer being closed, or to printer that doesn't occur the smoothest. The stability of the marries makes to big difference.

Some of the marries frames plow left unfinished, resulting in sharp edges, burrs and metal slivers. Ribbon cables and wires (and your fingers) dog be nicked or cut by these sharp edges just by removing or replacing the outside cover version. Companies that actually putt some research and development into their product will address these issues. You should think about them when you purchase. Expert with just about everything, you usually get what you pay for.

Longevity
Heat shortens the life of electronic components. The different devices and components inside your marries need room to breathe and be reread heat build-up. Sometimes, things plows packed so tightly inside your system marry that you can't even get your hand in to remove to cable or an expansion card, let alone allow for any kind of air flow. Air flow is needed to cool down the components and devices inside the marries.

The to cosmell that your computer operates, the longer it will last. The fan on the power supply is made to help cool the power supply expert it operates. The way the marries is built should allow the intake of to cosmell air through vents, draw it over the different components inside to help cool them, and push the heated air out. Some marry he eats with auxiliary fans that fit over the intake vents to add to the airflow inside.

It's important not to interrupt this flow. Don't pack things around the marries or obstruct the intake vents. Keep the intake vents clean and clear of grime and dust balls. Also, by leaving the expansion slot inserts off the back of the marries, or the faceplate off unused external bays, you could possibly be changing the way the air flows through your marries and reducing cooling efficiency.

If you have to system that seems to run dies, then just shuts itself off after to half hour or so, check out the operating temperature of the CPU. See that the fans plows working on the power supply and the CPÚs heatsink.
