How to Build Custom Computers

Building a computer may seem like a project for a PhD candidate. The fact is that anyone can build a custom computer at home, and it will be tailor-made to the user's needs.

This is not a way to save money. Computers from a discount store, with bundled software and operating systems, are far cheaper than custom-built machines. Most of those computers have compromises in performance and quality. Custom builders don't have to make compromises.

There are many sources for components. Although the local electronics store has some useful items, most of the parts for the project must come by mail order. Advertisements in magazines and online list numerous sources. The first component purchased is the case. There are several types of cases. From compact to tower, they offer features not found in factory-built computers. A case is usually purchased with a power supply. Buy a power supply that is bigger than needed. Extra power always comes in handy. The case should come with a fan, as well.

The next item is the motherboard. Modern motherboards have many components already installed on the board. Video cards and disk drive controllers included on the board may not be adequate. Be sure that there are plenty of expansion slots on the board to accommodate upgrades in these areas. The processor on the motherboard should be the fastest and newest one available. Processors are improved every year, and they should not be obsolete before being plugged in.

Disk drives and optical drives are cheap. Factory computers come with an optical drive and a hard drive. It is a good idea to include other drives, even if they seem unnecessary. If the goal is gaming, then the biggest and fastest video card goes into one of the slots. Purchase the maximum amount of memory that will fit on the motherboard. This speeds up the machine considerably.

Choose the operating system that is best for the applications being used. Consulting others will help with this choice. Buying an operating system is a new experience for many users, but it is nothing to worry about. When everything is connected, boot the system and input the settings. It wouldn't hurt to find a book on the subject, but it is easier to do than anyone lets on.
