There are optimized parts for a hackintosh, which is why it is best to DIY. As far as buying, the retailers will skimp on areas that are negligible or ignored by the consumer, e.g. motherboard, RAM, PSU. This makes it difficult to work with compatibility & OSX from a straight buy perspective versus choosing each optimized part in a custom build. As a warning, you might run into issues with seamless integration that is normally experienced with Apple products via MBP/iPhone/iPad. The 'ecosystem' doesn't like Hackintosh :D Seconding Korni22 and insanelymac forums.
