case statement to select multiple rows at once - sql-server

Question

I am looking to pull the same columns from two different tables, based on a conditional argument.
So i have stumbled upon the CASE statement which I have not used much before. I have found this will work for me in this mannor, but I would like it if I could do one CASE statement and then select the columns i need, rather then doing it per column.
Here is an example of what I have and working, just seems a little redundant.
SELECT TOP(10)
u1.userid as userid,
version = CASE
WHEN (u2.userid IS NULL OR u1.enabled = 0)
THEN 3
ELSE 4
END,
nameOrg = CASE
WHEN (u2.userid IS NULL OR u1.enabled = 0)
THEN CONVERT(NVARCHAR, u1.title)
ELSE CONVERT(NVARCHAR, u2.title)
END,
nameContact = CASE
WHEN (u2.userid IS NULL OR u1.enabled = 0)
THEN CONVERT(NVARCHAR, u1.contact)
ELSE CONVERT(NVARCHAR, u2.contact)
END,
pltName = CASE
WHEN (u2.userid IS NULL OR u1.enabled = 0)
THEN p1.name
ELSE p2.name
END
FROM
usr1 u1
LEFT OUTER JOIN
usr2 u2
ON u1.userid = u2.userid
LEFT OUTER JOIN
plt2 p2
ON u2.pltid = p2.pltid
LEFT OUTER JOIN
plt1 p1
ON u1.pltid = p1.pltid
Any advise?
Edit mov 7, 5:22: added join to plt table and pltName case, to add to required functionality.

In the case that there is no matching userid in the usr2 dataset, all the fields will be null. You could use the isnull function to make it a little less verbose as I have done below, but you won't get down to a single line.
SELECT TOP(10)
u1.userid as userid
,version = CASE
WHEN (u2.userid IS NULL OR u1.enabled = 0)
THEN 3
ELSE 4
END
,CONVERT(NVARCHAR,isnull(u2.title,u1.title)) nameOrg
,CONVERT(NVARCHAR,isnull(u2.contact,u1.contact)) nameContact
FROM
usr1 u1
LEFT OUTER JOIN
usr2 u2
ON u1.userid = u2.userid
