well, using the 50 pin and 68 pin internal connector at the same time would be bad as 
the
lines on the 50 pin connector would then branch off in 3 directions, which would be 
bad. 
as for not using the external connector, it shouldn't be a problem, you are allowed to 
use
a fairly long cable under the scsi specs.  i'd suspect that apple somehow used too 
cheap a
cable for the internal cable or failed to shield it properly, or ran it too close to 
the
metal case and increased the capacitive load or terminated things wrong or something 
along
those lines.  unless the card's design is drastically wrong you should be able to use 
both
connections at the same time.  this sounds a lot like the "special" terminator 
necessary
in the iifx, which apple claimed was because of the higher speed, but which was 
actually
necessary because their custom chip didn't conform to the spec fully and needed a 
little
help to reduce glitches.  it could also be a problem with the specific drive apple 
used if
it was slightly defective in design.  in any case, the stated reason about the cable 
being
too long is nonsense if everything else were done correctly.
