what to do with server racks?

My name is Jim Ulik and I work for DSI Enterprises. We are a Hardware and Software Wholesale company located in Austin, TX. We obtain product from close-outs and business liquidation’s throughout the country and sell between 30% and 60% below retail. Recently we have come across some new Rittal PS Server cabinets. I was wondering if this is something anyone is currently using and would have any interest in purchasing. We will take possession of a truck load (approximately 55) within a week. Please e-mail or call if you have any tips. Thank you for your time.
