Unless you have some sort of power on feature on your system it's never going top power on at 5AM. You could simply create to cron entries to up and down the network interface which would remove it from the network. If you really need to power it down you are going to have to have a way of powering it up at 5AM.

Another option is to get yourself one of those power adapters that you can control from a network connection. You could then setup a cron job on another computer to log into the controller and power down the system and then power it back up at 5AM.

If you are looking for just something on the system itself I am afraid you are SOL.

Some systems allow you to wake them up with a network message. However, I think that a system that is configured to boot on power-on would be more practical. Use a timer on the power line to turn on the power at 5am, and have cron shut the system down at 6pm. However, I must state for the record that it is actually better for your system to leave it running 24x7. Less stress on the hardware. You can setup cron to enable/disable the network interfaces at the appropriate times if you don't want to allow remote access outside of the specified hours and days of the week.
