If I could rate less than one star I would. I bought an expensive Dell 18 months ago and have now had two motherboards and three hard drives installed. I have a home business, so this has cost me time and money!When I talked with Dell management about replacing my system, I was told in a quite condescending manner that Dell doesn't do that; that since I have a warranty, they will just come and replace parts as needed for the duration of the warranty.I will NEVER purchase a Dell anything again and I hope anyone looking to purchase one will think twice. Obviously, their customer service stinks!
