So, at stock, my E4300 idles at 34C in TAT, which from the Core 2 Duo Temperature Guide over in the overclocking section means that the TCase (BIOS CPU) temperature is 19C (just subtract 15).

So, if the outerside of the CPU is 19C, then the surrounding air must be warmer. Now, its about 14-15C in the room, so would it be safe assuming that the actual case temperature is about 17C, just an average of the two?

If the air in the case were warmer than 19C then the CPU should start to form water...it's running on air cooling, so it can't do that.

The board actually reports the NB temp instead of case temp, or so I've been told that it essentially reports the NB temp, which is why in the BIOS my case temp is about 38C and the CPU is 19C.

But, I want to know how efficient my case is, that is how much warmer the air in there is than the air that's going into it...

Is what I've said actually right, tho?

Your reasoning is essentially correct, except there's no averaging involved. No temps in an air cooled computer can be below ambient. Since there are many variables involved, if users test their rigs as shown in the "Testing" section of the Core 2 Duo Temperature Guide, then post their info as shown under the "Results" and "Variables" sections, then a unique thermal profile is revealed, which can be used to analyze temps, and will show inaccuracies. Offsets can then be configured in SpeedFan 4.32 so that all 3 C2D temps can be accurately displayed.

Hope this helps,
