  Last I checked ES will print a message that this config is unsupported
during boot.  Other than that nothing else happens.  Of course if RH
realizes you are running an "unsupported" system they won't provide
support.  (This will likely happen as the 1st step of support is getting
the system information.)  So if you don't want support you could use ES,
but if price is your issue Centos is a better choice.
