A case's form factor vs a CPU's TDP

Are there any general "rules of thumb" when it comes to a case's form factor and a CPU's TDP? For example, for mini-ITX cases perhaps the recommended TDP might be <= 65W, micro-ATX cases <=95W, ATX cases <=125W, etc. In other words, how do I know if a case can or cannot handle the heat generated from a CPU? I know that a motherboard's TDP limitation comes first before a case's limitation.

Also, what about notebooks? I recently read about Intel's 45-55w mobile processors, and some people in those forums thought that was too hot for a notebook. Are there any recommendations for notebook TDPs?
 
There is no magic formula, since cases in different form factors have different cooling capabilities. An NZXT Rogue, for example, is a mATX case with better provisions for cooling than many ATX cases.

Generally though, the more heat being given off, the larger the case or laptop should be.
