Just because it's an AIO doesn't mean its better. There are plenty of air coolers that out perform AIO's for less money and becaue they don't have a pump air coolers don't have that extra point of failure like an aio. Temps of your internal components will be determined by your fan configuration. Where are you going to be mounting the aio? No mater what you do, if you choose to go with an aio, your cpu temps will always be low with that processor due to the tdp and overkill cooling. That being said, in order to have unobstructed air flow to the graphics card which will indefinitely be the hottest component, my advice is to mount the rad on the top so unobstructed front intake/positive pressure can hit the graphics card.
