1.3 Preliminary Tools

"A workman must first sharpen his tools if he is to do his work well". Right before you start the assembly, there are some tools that can't be spared.
Firstly, the most frquently-used too is cross screwdriver by which most interior componets are fixed. A suitable screwdriver can make the following job much easier. Being so, does any screwdriver apply? Actually a magnetic tip one is suggested. That is because in the process of setting up your PC, the situation is very likely to happen: you accidentally drop the screws into the interior of the computer. In case of this, a magnetic screwdriver helps attracting the fallen screws that are hard to reach by hands. Some screw holes are placed where hands can hardly reach. At this time, we need a magnetic screwdriver, too. In addition, the size of our tool also matters. Generally, the

When putting things together, it is necessary to adjust Jumper. In most cases, things can be done barehanded. But there comes a time always when your hands fail to reach in and fix the problem. You'll thank God with a pliers on hand which keeps you away from any annoying trouble for just setting one JUMPER.
is the most appropriate one.
What is Jumper?
Jumper is something generally referred to " Jumping wire" that utilizes the short circuit o the pins to tune up some functions, such as FSB (front side bus), ratio, and sound switches adjusting.

2.3 Set Up I/O Back-panel
The H300 housing series are equipped with all-purpose I/O back-panel. You can break through the openings according to your personal needs. If your motherboard comes with built-in sound effects or network functions, then you may need more openings to connect to external speakers and network connection.
Check I/O connector ports on the motherboard with your housing and decide
which openings you need to break through.
If there is a built-in network card on the motherboard, then you need to brea through this iron plate.
If there is only a built-in sound device, then you need to break though these two iron plates.

2.4 Set Up Hard Disk

In the structure of personal computer, hard disk is the place where most of the data is stored. Therefore, it is one of the most important components in personal computer. This section will introduce you the knowledge of hard disk and some important tips while setting it up.
Get to know hard disk
Taking out the hard disk from the parcel, you will see the following equipments:
Adjust the Jumpers on your hard disk
Jumper configurations
As mentioned, we assume you know the definition of Jumpers. The setting of Jumpers in IDE
hard disk is necessary for a computer to distinguish various devices connected on the same cable. In general, we normally set hard disk to "Master", indicating the first device of the cable; then we set CD-ROM to "Slave", meaning the second device of the cable. The settings of the Jumpers are marked on the tag attached to the surface of the hard disk or are mentioned in its handbook. Here, we only set up one hard disk, so that means the jumper has to be set as "Master."

Jumper here is set as "Master"

Connect IDE cable
It would be easier to carry out the procedure if the IDE cable is properly plugged before locking up the hard disk to the frame. You can distinguish IDE cable from left and right. Normally, a standard cable has a foolproof device, which is a small salient on the cable, and a small dent in the socket. Just aim the salient at the dent and then plug it in.
The first pin is close to power connector.
What if there is no foolproof device
Lock the hard disk in the frame
on the cable?
If you happen to have a cable without foolproof design, just remember that the first pin is next to the red line and it would be safe to locate the first pin close to the power cord
Use a cross screwdriver to disassemble the hard disk frame from the housing in order to easily lock the hard disk. After loosing screws, lift the hard disk frame and push it to the direction where arrow shows to draw it out.

In fact, hard disk is a very fragile and delicate device though it's covered with robust metal. During the process, any slight vibration may damage it. Hence, be sure to get it locked in the fixed frame securely.
Don't mess up screws!!
Pack the fixed frame back to the housing
Put the hard disk frame back to the housing and lock it securely to complete this step. It's pretty simple: Just aim two tenons on the fixed frame at the housing and push it to the opposite direction.
Generally there are special screws for hard dis in the parcel when you buy a new hard disk. There will be no harm done using those screws. If no screws are attached, use those packed in the accessory parcel. Make sure to use the NO2 screws.

Read the handbook of the motherboard and adjust the settings of Jumper
Currently most of the motherboards have a Jumper-free design (Jumperless design). Even so, there are still some other functions that need to be adjusted through Jumper. Please refer to the handbook of motherboard and adjust the settings of Jumper according to your personal requirements.
Please refer to the motherboard handboo to adjust the settings o Jumper according to your needs

2.14 Set Up Interface Card

If there is no built-in VGA card in your system, you have to choose a suitable one. Read this
section carefully if you desire to install other interfaces (such as network card, modem card, image card, or 3D-acceleration card). We take VGA card setting up as an example to demonstrate how to set up an interface. The set-up of other interface cards is very similar.
Different interface cards not only vary in outlooks but in sockets!
This is AGP socket that is usually brown. It is a high-speed interface specially designed for VGA cards.
These are PCI sockets and they are usually white. They can be connected with various interface cards.
AGP interface card: Generally only VG
card applies to AGP interface. However, most 3D acceleration cards apply to AGP interface as well after integrating the displa function.
