In short.  Physical access trumps all other locking mechanisms anyway.

CPU servers were not meant to be workstations, and the lack of a screen lock
shows that.  But then workstations are easily stolen.  2 were taken from the
building where I work in the last weeks at a law firm office (we share our
building IANAL), and no amount of screen locks saved those.

However I still screensaver lock my desktop when I leave for the weekend.
 Not that it'd matter, if someone really wanted my data they could get it.
