I will add one thing to what everyone else has said. VERIFY that the server hardware will support virtualization! I got bit by this when planning our move to virtualize all of our servers. One machine has the chip the other does not. From the pricing and age you are talking about my guess is you will not have the necessary chip. This will limit what you can and can't do with virtualization.
