Evaluate benefits of purchasing desktop PCs

Due to their mobility feature, laptop and notebook computers are very popular in the business market. They allow professionals to review files and close deals from any location in the world. However, despite recent decreased pricing on notebook and laptop computers, desktop computers are still the most affordable choice. In addition to price, desktop PCs offer more power than mobile computers. As a result, many businesses find it necessary to purchase both laptop and desktop computers.

Tips& Tactics for Desktop PC Purchases

Helpful advice for making the most of this Guide

• •  Desktop personal computers can be purchased new, used or refurbished. Used and refurbished desktop computers generally cost less than new desktop PCs. While price is important to your budget, there are a range of other factors you should review when shopping for new, used or refurbished desktop PCs including memory capacity and upgrade options, hard drive size and computer processor types.

Although any desktop PC can be used for business, you can end up paying more than you need to if your desktop computers have a lot of bells and whistles you'll never use. Most small businesses don't need whiz-bang multi-media capabilities, an analog modem, hand-holding software or a cosmetically chic case. You do need:

1. Reliability and serviceability.
2. The option of paying for what you need only.
3. To spend between $600 and $1,000 for a desktop PC that includes Windows and no other software.

Look for a tool-free-access mini-tower desktop PC case

The cases for your desktop computers must be big enough (at least as tall as a 17' monitor) and spacious enough to adequately dissipate heat. The power supply should be at least 350 watts. Access for repairs and upgrades should be quick and easy.

I recommend: See comparative pictures of desktop PC form-factors offered by Dell in the manufacturer's Precision and OptiPlex lines. Or consider another computer vendor.

Consider a dual-core processor (CPU) for your desktop computers

Dual-core CPUs may be pricey, but they generate much less heat than single-core CPUs, which will enhance the reliability of your desktop PC. Consider Intel Celeron CPUs for desktop computers that will only be used for clerical work.

I recommend: Webopedia lists the current AMD and Intel CPUs, and explains the differences among them.

Choose an appropriate desktop PC hard drive

For business use, hard drive speed is as important as size (capacity). Opt for an SATA or SATA II hard drive. It should spin at 7,200 or 10,000 RPM and have an access time of about 9 milliseconds. Capacity isn't critical, because you can easily upgrade on that.

I recommend: PC Magazine has some advice on selecting hard drives for your desktop computers.

Choose a removable media drive for your desktop computers

You need at least a CD-ROM drive in your desktop PC but should probably opt for a DVD-RW drive instead, especially if you aren't backing up to an external hard drive or server. DVD-ROM drives and floppy drives are generally unnecessary for business use.

I recommend: Check newegg.com for prices on DVD-RW drives from various suppliers of desktop computers.

Weigh the advantages and disadvantages of integrated video in your desktop PC

Most business desktop computers have a video chip on the motherboard. This is cheaper than having a separate video card. However, desktop computers must dedicate a certain amount of RAM (often 128 MB) to providing a display. Also, when the video chip overheats or dies, you're likely to need a new motherboard.

I recommend: Use the PC Magazine directory to compare the prices offered by various suppliers of desktop computers with and without integrated video.

Determine how much RAM you need from your computer vendor

If the computer has integrated video, you will need at least 512 MB of RAM. If it has a separate video card, 512 MB of RAM should be adequate for running Windows XP. Windows Vista will require 1 GB of RAM.

I recommend: Kingston, a memory manufacturer, offers a conservative guide to determining how much RAM you need for various typical computer uses.

Make sure the desktop PC motherboard has enough ports and expansion slots

Look for an Ethernet port and whatever USB or FireWire ports you need for your network. Make sure the motherboard has open RAM slots, an AGP or PCI-express video slot, and open PCI slots for future use.

I recommend: This diagram shows and explains the standard connectors on the back of desktop computers. Zoom in on this picture of an ECS motherboard to see an example of internal slots for DDR memory, add-in cards and video cards.

Consider desktop PC service and support options

Get desktop computers with a 3-year warranty or pay your chosen computer vendor to upgrade to a 3-year on-site warranty unless you have an in-house support and repair solution. Be aware that you may find the tech support provided from the Third World or the warranty service provided by third parties inadequate.

I recommend: Check the PC Magazine subscriber survey, published each July, for comprehensive information about reliability and customer satisfaction with individual desktop PC brands. Also check the directory on Business.com for more information on desktop computers by brand.

Consider refurbished desktop computers

If you find costs to be too high even with the above suggestions, you should also look into refurbished desktop computers. Even the biggest computer vendor now offers them, and they can be a a great option for those who want to have some extra bells and whistles on the cheap.

I recommend: Check the directories on Business.com for more on refurbished desktop computers.
