Decide what computer components you need

Before buying computer parts, you should know not only which parts you need, but what each does. An informed shopper always finds the best deals on computer hardware.

I recommend: Read Wikipedia’s entry for “Computer hardware” and Build-Your-Own-Cheap-Computer.com’s “Cheap Computer Parts” guide to familiarize yourself with your computer’s insides. Computer hardware organizations, such as those listed at Business.com, are also a good source for information.

Compare computer hardware prices online

Internet retailers generally offer the best prices on computer hardware. Visit several Web sites, however, before you click “Purchase.”

I recommend: Compare the cost of computer components online by searching for the computer parts you need—by product name or model number—at BizRate or Shopzilla. Or, go directly to your favorite online computer retailer; TigerDirect.com and Newegg.com generally have the best deals.

Buy cheap computer parts offline

If you prefer to do your shopping at brick-and-mortar businesses, consider hunting for cheap computer components at smaller, local computer retailers. Mom-and-Pop stores are likely to have not only the best deals, but also the best service on the computer hardware you buy.

I recommend: Computer Renaissance is a computer parts and repair franchise with top-rated prices and customer service. Not in your area? Ask local techies—you can find them via Google Groups or AOL Message Boards—where they shop. Finally, visit computer hardware industry events, like those listed at Business.com, for unique offline deals on computer components.

Look for used computer components

If you need a great deal on computer parts, consider buying used, refurbished or recycled computer hardware. Computers grow old quickly, after all, but their individual parts are often ageless.

I recommend: The Open Directory Project has dozens of links to used computer hardware dealers worldwide. Don’t forget eBay or computer hardware manufacturers themselves, such as Dell or HP, which sell refurbished computer components via outlet stores.

Sweeten the deal with extra computer components and accessories

Cheap computer parts will make your computer work, but cheap computer accessories—such as a printer, speakers, a scanner, a digital camera and a Webcam—will make it fun.

I recommend: Don’t forget basics like a computer monitor, keyboard and mouse, which you can find online at Business.com.

Don’t forget the operating system

Computer parts are your PC’s bones, but an operating system is its brain. Choosing a smart OS will increase your machine’s efficiency and your own productivity.

I recommend: There are three main operating systems for the modern computer: Windows, Macintosh and Linux. Versions of all three can be purchased from CompUSA.

Install your new computer parts

If you really want to save money, don’t just buy your own computer components; install them, too.

I recommend: To install your own computer parts, you’ll need a computer toolkit, such as those at Amazon.com, which have tools designed specifically for computer hardware installation, and antistatic equipment, such as wrist straps and bags from ESDProduct.com, which will protect your new computer components from the static electricity that can damage them.
