From my experience HP build good reliable equipment. I have a seven year old CD writer and even older printer which have neen faultless. Main computer is a two year old W5470 which has again been faultless. Cannot speak for their service as never had to use it. Their case design is good and there is no warranty problems on opening it and adding eqipment. The spec. of the A6140 is pretty good. How does your price compare with John Lewis?
