Query On Case structure

Hi All,
Can we create a query to find different values based on different criteria from a table using case structure. For example

Select Into DBComment
Case When localComment Is Null Then Comment
When localComment = '123' Then 'Numeric Comment'
Else 'String Comment'
End
From PDBUser
Where UserIndex = 23;

Using such type of structure can we evaluate multiple values. e.g

Select DBComment , DBName
Case When localComment Is Null Then Comment
When localComment = '123' Then 'Numeric Comment'
Else 'String Comment'
End,
Case When localName Is Null Then UserName
When localName = 'SuperUser' Then 'Supervisor'
Else 'NormalUser'
End
From PDBUser
Where UserIndex = 23;

Is this possible. If yes then How is it.
Any help/suggestion may be benificial.
