True, you can use just 600W for your SFF or HTPC but, why stop there? As good as manufacturers try to make their 1000+ units, they will inevitably add to the case cooling problems. Leaving the PSU outside of the case is a logical solution. If the market continues in the direction of consuming more and more watts, you will have to finally choose to either go external or noisy. The first choice may not look very stylish to you, but that can be improved. On the other hand, avoiding noise on a device that has to dissipate, let's say, 150W of heat in such a jammed space, without fresh intake air is impossible. Water cooling could do that, or a separate chamber for the PSU (like Antec does). Both solutions relay on the same principle behind the external unit, using outside air for cooling.
