Blair refurbishes computers and I got the 8GB ram which doubled my old computer and 500 GB which is more than I usually ever use but since I don't put a lot on my computer, it is extremely fast and works very well.  Rather than buy a new computer, you might just check the Blair Techology refurbished computer website and save some money while seeing that these people know what they're doing with getting old computers back to a workable great product.  It also comes with Windows Pro and other features that made it easy to set up.
