1. Plan for future growth. Look for a server that can be scaled up as your requirements grow.

2. Look for a system with server-specific features, such as specialized server chipsets, I/O performance, and high-speed SCSI drive arrays.

3. If your business is likely to suffer financially from a server outage, buy a server that includes readily available components and software, to minimize downtime.

4. Choose a manufacturer that bundles a comprehensive, easy-to-use management suite as part of the server package.

5. Don't forget to include operating-system costs when pricing servers. Unlike desktop systems, most servers do not include a preinstalled OS. This can add another $800 or more to the price tag.

6. If your organization has little or no IT staff, consider a value-added reseller (VAR) that will do a free on-site assessment of your infrastructure to help determine which server best fits your business requirements.

7. Determine how much room you want to devote to your network infrastructure now and in the future. Tower systems are fine, but if you have serious space constraints, a rack-optimized server may be a better choice.

8. If you go with a rack-mounted configuration, remember to factor in the costs for racks and accessories such as cabling trays and power supplies (including rack-mounted UPS devices).

9. Buy from established manufacturers or VARs. In going with a lesser-known manufacturer or reseller, you run the risk of having nowhere to turn for warranty service or support.

10. Warranty service should be three years with next-day, on-site service (except for value models, which usually come with one-year warranties).
