This applies to a wide range of electronics, not just computers. Rather than resort to daunting, expensive, or complex (all three tend to go together) cooling methods, there are many ways in which you can utilize natural physics to cool components cheaply and effectively. The picture on the left looks awesome, but is expensive if not complex. Lets face it, it is just as cool - if not more - if you can harness nature through your own cheap resourcefulness to get the same performance.
