bought this refurbished unit as a backup. Unit was in excellent outward appearance. Was able to configure it,  but it started having hard drive issues and would crash. Returning the unit, Amazon makes this very easy.. This is the chance you take with a refurbished unit, some small portion of them crash.. I will probably try another refurbished one in a month or two. The computer (if it is good working order) is a great unit for business. being able to buy a refurbished one for 1/3 of new is worth the chance of getting a bad one and having to return it, imho.
