I'm not sure what you mean by "mounting the NST inside the case".  Do you
just mean near the primary?  I performed some experiments to determine the
effect of locating the NST near the primary coil.  At a distance of roughly
a foot, there was a small loss due to eddy currents in the metal of the NST.
Losses grew worse as the NST/primary space narrowed.

After testing the new cap from Sundog and the NST I have, I mounted the NST
inside the case and hooked it up and noticed that the sparks were slightly
shorter as if the proximity of the NST ~7" was warping the magnetic field of
the flat primary. 

Maybe, a setup where the NST were external or positioned differently, would
be more efficient.
