I am generally leery of the idea of removing extreme values.  It is important to look for extreme values in order to check that the data was correctly entered. However, depending on the nature of your data extreme values may be particularly interesting.

What is the nature of the cases? Are they a pop, a genuine sample, an available set of cases? etc.

What is the nature of the set of variables?

Why is data missing? Do some variables account for much of the missing data? I.e., could you retain more cases by dropping variables?
