Since deciding to build my own system I have endlessly searched the internet for some of the best and most detailed videos on it. After viewing multiple videos multiple times I have determined this one to be the best. Not only will it answer you questions on figuring out compatibility of parts but it even makes some suggestions on processors, after-market heatsink/fans etc. Enjoy
