Guys, Im thinking of replacing the Hard Drive that comes stocked with the mac pro because its way too noisy. Im looking for a 7200RPM hard drive, with good storage, and less noise compared to the one that comes with the Mac Pro. Between 200-300 dollars. I was reading good reviews on the Maxtor MaxLine Pro 500, will it work with the Mac Pro? Also, Im planning on buying an extra 1gb of third party ram, wich one do you recommend? 1x1gb or 2x 512mb? Also best place to get them online. Thanks alot!
