I purchased this computer for $579.99 through Amazon. Amazon is my favorite. I buy everything from amazon and am always happy.. It was fine. after a year and a half approximately the mother board died. I called the sellers. They said it was out of warranty by a few months. Ok. They said they would repair the mother board for $419.  This response was from Acer. THey referred me to a parts company that they said would give me a better price. The company was Capital Data. They said they would sell me the motherboard for $575 and I would have to hire someone to install it. Obviously I will  never buy an Acer product again. They could have tried to make me happy somehow but they offered nothing.  It's possible that they could have offered me a motherboard for a little discount. They chose to allow me to be very displeased with their company and I am. Of course I still am an amazon customer. But will never buy an acer product and will look very carefully at what Amazon backs up and what they don't. Big lesson for me.
