Interestingly, the Lite versions offered in Korea do not have the 
connector blocked off:

I'm not certain as to the discussion Micheal & Luis are reffering too, 
but I would define the "frontend" of a card as being the both the tuner 
and demodulator(s). When the demodulator(s) is/(are) contained within 
the metal housing surrounding the tuner you will often find this 
referred to as a NIM (Network Interface Module) or, less frequently, as 
a ITD (Integrated Tuner Demodulator).    But a frontend need not  have 
its demodulator(s) contained within the tuner section -- examples of 
which are the pchdtv cards, which have their Oren demods exposed on the 
surface of the cards
