Another consideration is the OS and other software you need. Prebuilt systems nearly always arrive
with the OS installed, but when you build your own, you must be prepared with a copy of your
selected OS.
The OS you select for your new computer is another important decision. You must be certain that the
OS supports all the hardware you've selected, which can occasionally be a difficult task. Today the
main choices are Windows or one of the Linux variants. This is one area where building your own
has real advantages; OEM systems often have limited choices when it comes to the OS, but when you
build your own system, the choice of OS is entirely up to you.
Drivers for the desired OS and specific hardware components might also be a problem. It is a good
idea to gather all the latest driver revisions for your hardware and intended OS, as well as BIOS
flashes, firmware updates, and other software components, and have them available when you begin
the assembly process. Placing them on an optical disc or flash drive is a good idea; that way you can
access them easily and install them when necessary.
System Assembly and Disassembly
Actually assembling the system is easy after you have lined up all the components. In fact, you will
find the parts procurement phase the most lengthy and trying of the entire experience. Completing the
system is basically a matter of screwing everything together, plugging in all the cables and
connectors, and configuring everything to operate properly.
In short order, you will find out whether your system operates as you had planned or whether some
incompatibilities exist between some of the components. Be careful, and pay attention to how you
install all your components. It is easy to forget a jumper, switch, or cable connection that later causes
problems in system operation. Most people's first reaction when problems occur is to blame
defective hardware, but that is usually not the source. The problem can typically be traced to some
missed step or error made in the assembly process.
Above all, the most crucial rule of assembling your own system is to save every piece of
documentation and software that comes with every component in your system. This material can be
indispensable in troubleshooting problems you encounter during the assembly process or later. You
should also retain all the packing materials used to ship mail-order components to you until you are
certain they will not have to be returned.
Assembly Preparation
The process of physically assembling a PC requires only a few basic tools: a 1/4-inch nut driver or a
Phillips-head screwdriver for the external screws that hold the cover in place and a 3/16-inch nut
driver or Phillips-head screwdriver for all the other screws. Needle-nose pliers can also help in
removing motherboard standoffs, jumpers, and stubborn cable connectors. Because of marketplace
standardization, only a couple types and sizes of screws (with a few exceptions) hold a system
together. Also, the physical arrangement of the major components is similar even among different
manufacturers. Figure 19.1 shows the components that go into a typical system, and Figure 19.2
shows the system with those components assembled. Note that the components shown here are for a
standard PC. Your final component list might vary.
