There are a few different types of computer servers: tower, rack and blade. Computer server towers are sometimes called pedestal servers. They are assembled in an upright cabinet as opposed to blades and rack servers, which are rack mounted. Tower servers can be used to share files and printers or to run websites, databases or network applications.

Although tower servers have been on the scene for years and are still produced, rack mount servers are becoming more of the standard new server purchase. Still, there are some advantages to purchasing a computer tower server, including:

1. A tower computer server doesn't need a rack to support it and can be used right out of the box.

2. A tower is easier to cool.

3. A single tower server doesn't take up much room and is easy to store.

Action Steps for Computer Server Selection
The best contacts and resources to help you get it done

Purchase a new computer server tower

Server manufacturers produce tower servers in a range of prices, processing power configurations, memory and hard drive capacity.

I recommend: Dell PowerEdge servers are avilable with dual or quad-core processors with one or two sockets. The IBM xSeries towers are expandable with dual and quad-core processing and memory up to 48 GB. HP ProLiant ML servers are available in a range of configurations to meet various processing needs.

Find used computer towers

You can find used and refurbished tower servers at low prices.

I recommend: Contact Vibrant Technologies for a quote on a new, used or refurbished IBM xSeries tower server. Key Services Midwest offers used HP ProLiant servers.

Get custom computer towers

A custom server builder can create the system that is just right for your computing needs.

I recommend: NixSys builds custom servers with Intel Xeon processors, up to 12 GB of memory and expansion bays that offer room to grow. Thinkmate creates custom Intel Pentium and Xeon systems. If you need custom tower cases for your server that really stand out, choose from the selection at Systemax's TigerDirect, which includes cases with clear sides and various colors and designs. Specialty Cases builds custom cases that keep a server protected during transport.

Tips & Tactics for Picking a Computer Server

Helpful advice for making the most of this Guide

• •  Find out about warranty and return options before purchasing a used or custom computer tower server from an online retailer. The company may offer a short warranty period or no warranty at all. Also inquire about the requirements for returning the unit if it doesn't function to find out if you are liable for the cost of shipping and restocking.
• •  Refurbished computer server towers are often sold without hard drives, processors or other hardware. You'll need to purchase and configure the necessary parts before using your server. You will also need to purchase an operating system.
