I will jump on the bandwagon of not getting the convert to char but will point out that I never like code that just uses the default size for datatypes. I don't like to have to stop and think (or more likely lookup) what the default size is for a given datatype.
This is so much easier to read exactly what is being returned:
SELECT CONVERT(char(30), DATABASEPROPERTYEX('AdevntureWorks', 'Collation'))
