Dell Dimension desktop PCs have been Dell's primary offering to small business for several years. The Dell Dimension computer is an affordable computer with up-to-date technology and processing power. They have the flexibility to work as stand-alone or networked computers.

Dell Dimension desktop computers are becoming difficult to find. Dell offers a limited number of new models. The Dell Dimension is being phased out, with similar configurations being marketed as Dell Inspiron or XPS computers. If you want to buy a Dell Dimension computer or have one that needs repair or upgrade, here are some things to keep in mind:

1. You can find new and refurbished Dell Dimension computers at Dell's website and from other suppliers.

2. Parts for the Dell Dimension are widely available.

3. Dell Dimension computers have been on the market for many years, and reviews vary by model number.

Parts for the Dimension are available from many sources. Some parts, like memory and power supplies, are proprietary or specialized. Verify that the parts are compatible with your model number before purchasing.

I recommend: Impact Computer Computers and Electronics and Discount Electronics sell a wide range of parts, including Dell Dimension memory, power supplies, CDROM drives, hard drives and even computer rails.

Read reviews before buying

Before buying a used Dell, check reviews for the specific model you plan to purchase. Dell Dimension has been around for years and is widely reviewed.

I recommend: CNET and PC Magazine are two of the sites that offer archived reviews of many Dell Dimension models. Most models have received very favorable reviews. A few have been panned - most notably 2003's Dimension 4600, which PC World listed as one of the worst PCs of all time.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Private sources like local or online classified ads can be a good source for used Dell Dimensions. If you are considering purchasing a computer through a private sale, make sure the Dell driver disk is sold with the computer.
• •  If you buy a used Dell Dimension, you may have to supply your own Windows operating system. Keep this in mind when pricing a used computer. Make sure the memory, processor, and hard drive space will support the version of Windows you plan to install.
