Find new and used Dell Dimension desktop PCs

The best place to find Dell Dimension computers for sale is through Dell, which offers used and refurbished models as well as new ones.

I recommend: New Dell Dimension towers and small form-factor desktops are available on Dell's website. You can find a variety of used and refurbished Dimensions through the Dell Financial Services store. The Dell Outlet offers refurbished and left-over Dell Dimension desktop computers.

Get parts for your Dell Dimension

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.
