Here is a note on Computer Warrentees, If you are the kind of guy that likes to upgrade about every six months to a year, system warrentees are usless, as by the time three years have gone by, you may not have any of the original computer in its original configuration! In most cases, warrenttes limit you to going to the store that you bought the computer from and paying them to install the new hardware. Also, if you do break anything in system warrentees when trying to upgrade the Hardware, the warrenttee is N/A. Do yourself a favor and buy the parts you know are best for what you are using it for and build it yourself. you may have problems at first,getting them to work together but in the long run, you will appreciate your system a whole lot more than picking the parts some store want you to have.
If it works for you then don't fix it.
