A:Answer Only that any all-in-one is very limited, if at all, for upgrading. Remember when buying computers of any make and model, particularly off the shelf units, the specs always list major components used in the build but never mention the important things like the chip set used on the motherboard. If this is of low end quality the processor itself can be very limited due to the limited features of the chip set. A bottle neck in performance occurs which makes some of the processors used pointless.
My suggestion to you and anyone buying a computer is to check and see if that model will run the software you will be using. If only using applications like Office, which is not very graphics intensive at all, then a lower end computer is fine. On the flip side, if your apps are games or CAD then you want the best you can afford. If you cannot buy the best then make sure you buy with upgrading in mind. The all-in-ones are on the very low end as far as specs and adaptability. Be very informed before making your purchase.
