If you have a wired interface marked for DHCP, but no cable plugged in,
and ONBOOT=yes, the network service will block waiting until the DHCP

Many of the features of NetworkManager do make life easier on desktops
and aren't as useful on a server machine. So if you're just interested
in servers, the story shouldn't be any different with NM than with the
'network' service, except that NM provides a single source for
information about the network that programs can query.
If you're using a single ethernet adapter, statically configured,
without a desktop, and only running say httpd and samba, then no, you
probably don't want to use NM. You certainly _could_ if you wanted to.
If we're talking about GUIs, or more mobile machines like laptops or
mobile internet devices, or desktops in general, or multi-user systems
where finer-grained control of network devices is desired, then I can
list more advantages of NetworkManager.
