To be quite honest, you don't need any of it unless you plan to OC. The H80 would be a nice cooler to keep your CPU cool without a ton of noise from the stock fan. Then again, so would a Hyper 212. The Hydro series is a closed sealed loop so no upgrading of the parts, leak testing, or air bubbles. Just mount and go. I just suggested the H80 because I feel massive chunks of metal aren't needed anymore.
