Dell's Optiplex PCs are a common sight on the desks of corporate users across the country and around the world. I recently looked at the Dell Optiplex GX620 ($1,535 direct, $1,247 without monitor), evaluating it from the perspective of the small-business owner. I define a small business as any company consisting of 1 to 100 employees that, more than likely, does not have a full-time IT staffer. The Optiplex GX620 line will feel right at home in businesses like this, especially ones with big plans of explosive growth but not much in the way of technical resources.
