You will probably be right buying a kit of parts, what you tend to end up doing is ending up upgrading half of the parts eventually, if you go for a bundle lot of them dont include hard drives or an operating system, but theres nothing stopping you reuseing the ones youve already got, just need to get hold of a clean copy of install disc and reuse the key on your current computer and the hard drive is in good condition.
