[CentOS] About download ISO image, again

Hi folks,

It comes to my notice that there is an server version -
CentOS-4.4.ServerCD-x86_64.iso
http://mirror.myriadnetwork.com/centos/4.4/isos/x86_64/

I'm going to run CentOS as server.  What packages are included there?  

Is X packages included as well which should not be on a server creating
a risk hole.  However on another hand it will be convenient for me at
the early stage of installation to search documents on Internet.  Just
retain X not started at boot and remove all their packages after
installation finished.  I don't expect connecting a workstation to the
server to do this job at the beginning.

Advice would be appreciated.  TIA
