Your office computer network is probably the backbone of your business. It stands to reason then to make sure things are configured and running smoothly. Imagine what would happen if a fire breaks out, or thieves break in, and you lose your computer with critical data? A backup solution is imperative, including a list of all CD keys and CD images that you have running, so that you don't have to try to hunt down older software versions when reinstalling on a replacement PC. Also, keep in mind that dust build up inside the PC case can overheat components, and cause major failures, and a regular maintenance schedule is recommended.
