if your looking for something to practice on, something older, perhaps a old custom build with like a pentium like captain suggested, with a PSU upgrade and a heatsink upgrade. Realistically, with a $300 max price range, your not likely to be able to build a new computer that will do basic computing, not alone any kind of a serious overclock anyway. go older, go used, until you get good at it, and then purchase new equipment, and save up for a solid setup.
