Project Air Cube - Going back to air

It has been a long time (about 7 years) since I have built a computer without water cooling. This project is going to be a little different then some of my past computers. Those have always been geared towards extreme performance, and while I will of course be overclocking this as much as I can, it will be air cooled (so there will be limitations). The idea behind this is more of a very quiet multimedia/multiuse computer.
