Unnecessary Services FedoraCore7 Home Desktop

I recently installed Fedora Core 7 on 1 of my virtual machine host at home but I noticed that there are many unnecessary services running, eating lot of RAM so I disabled those.

[root@localhost stuff]# service auditd stop
service avahi-daemon stop
service bluetooth stop
service haldaemon stop
service hidd stop
service ip6tables stop
service iptables stop
service mcstrans stop
service mdmonitor stop
service ntpd stop
service pcscd stop
service setroubleshoot stop
service restorecond stop
service firstboot stop
chkconfig --level 0123456 auditd off
chkconfig --level 0123456 avahi-daemon off
chkconfig --level 0123456 bluetooth off
chkconfig --level 0123456 haldaemon off
chkconfig --level 0123456 hidd off
chkconfig --level 0123456 ip6tables off
chkconfig --level 0123456 iptables off
chkconfig --level 0123456 mcstrans off
chkconfig --level 0123456 mdmonitor off
chkconfig --level 0123456 ntpd off
chkconfig --level 0123456 pcscd off
chkconfig --level 0123456 setroubleshoot off
chkconfig --level 0123456 restorecond off
chkconfig --level 0123456 firstboot off

So I got pretty good results while running X,fluxbox and firefox
