Most business users don't have time to hassle with taking a computer to a retail repair shop. Why make customers go through the process of unplugging all the wires, packing the PC up in the car, dropping it off for several days, going back to pick up the PC and attempting to set it all back up again?

In extreme circumstances CITC will pick up the PC, repair it and deliver it back to the customer ready to plug in.
