My favorite would probably be the kuhler 1250 because of how well it works, my rig currently is in a antec p280 so it would match nicely.
The power supply is also amazing, the build quality and looks although i don't like how its not blue because my rig is white/blue
The finish to the build just looks amazing, the red cooler, the fully white case, and the amazing cable managment.
This video answered one of my biggest questions because I thought the aa option was useless at first until I saw the video.
