After 54 days of running server I'm ready to decide what services should stay and what were not used thus not needed.

No one even notice that they are down. And if I really need one it's just a meter of spinning it up.

There are still plenty of free disk space.

And the system is running cool.

I'm still don't have automatic backup solution. But I did a manual backup. So this will be the next big thing to work on.
