Will smaller cases give me better cooling of all my PC components or will bigger cases with the same fan setup?
it depends on the airflow.
Each case is different. But they can all adequately cool your system, unless you are looking into overclocking. Then you need to do more reading about how to keep your processor cool - better heatsinks, etc.
Are you building your own PC? Make sure you put the heatsink on the processor the correct way, and make sure all fans are connected correctly. Also, if things overheat, it will shut down your computer, not wreck the thing.
-----------------------
to the fellow that votes for "bigger case" - Why?
Picture this - i have a very small case with the fan blowing directly on the processor; wouldn't you say it is staying cool?
And picture this - i have a huge case where the fan is blowing in one corner and back out a few inches away, without causing any airflow to the processor. Wouldn't you say the smaller case is better now?
