You cannot use a corporate key on anything you intend to sell. Corporate VL all use the same key for all the systems in the company up to 500. You need a bulk OEM deal, and the price you get will depend on how many you purchase. Companies that buy over 300,000 licenses at a time get a special deal and also get license agreement compromises that allow them to burn their own system discs. For the average system builder you will be better off buying the OEM version from discounters such as newegg.
