We are a Dell Premier Partner, and we offer complete Dell computers with on-site support provided by Dell’s network of service technicians. The only exception to this rule would be computers bundled with some brands of equipment (not itemized, but listed in the product description), as these are sourced by our suppliers and shipped with software pre-installed for your convenience. A complete computer system consists of a CPU, display, keyboard and mouse. These systems list very basic specifications because it is impossible to maintain the latest specifications here at all times. We tune these basic configurations to your specific requirements and deliver the latest technology available at the time of order. We list relatively generic configurations here for convenience, but because technology evolves so rapidly we are committed to offering the latest technology available at the time of order fulfillment. The configurations we list are in a desktop/mini-tower form factor, but a notebook can be supplied for most applications for a slightly higher price.
