How big would an 'Eastenders: The Complete Boxset' be?

How much physical space would a boxset DVD of every episode of
Eastenders take up? I know Coronation Street has been running longer,
but I've never watched it - it has too much of a depressing theme
tune, I don't like that cat on the roof, and I've never watched beyond
the opening credits.

Eastenders is a long running British Soap Opera if anyone was unsure.
