KBM Enterprises has been a Dell Value Added Reseller for many years. We have several supported Windows Exchange servers and most of the desktops that we put in a business environment are Dell custom configurations prepared by a KBM Consultant. I would never suggest that you buy a pre configured Dell. Customizations are always necessary and without knowledge of the component technology, you can get a nasty (that's techy for you will not be happy with it) machine. If you do not have a working knowledge of current technology, please contact us so we can prepare a Personal Shopper Page for you. Even if you don't like the Dell we suggest, the page will give you lots of information to help you compare machines from Dell and other vendor. We have just augmented our relationship with Dell to include a commission based relationship May, 2007. While there is a link on our home page, we are still in a bit of a quandary whether we really want you to use it. Prior to May 2007, we strictly provided Dell recommendations at cost and provided separately billed hardware consulting services, software consultation, and network design. If you are not a technologist and/or you don't want to call KBM, please call Dell or read their explanations carefully.
