Mixed DHCP and static IP configurations is a very useful but often 
neglected combination. [1]

Every OS I've used requires some hacking around to make it work as 
desired.  The only reason Linux is easiest of the bunch is because it 
has a history of letting you turn off the automation, so you can prevent 
it from doing undesired things.

Windows is far worse than CentOS in this regard, NM or no. [2]

[1] A machine might need to accept a random DHCP IP in 192.168.0.x to be 
allowed through the LAN's restrictive Internet gateway but also need to 
have static IP 172.16.17.1 to serve a set of Internet-disconnected boxes 
in that same /24 scheme.  This is easy with all modern OSes if you have 
two NICs and two Ethernet connections back to the nearest switch.  Not 
so easy when both purposes must be served by a single NIC.
