Reinstalling OS X server on headless Mac mini I have just started the Mac Server Essentials certification course and I'm stuck at chapter 1!

I have a MacBook Pro, a Mac mini server and a WiFi router as a switch between the two. I don't have it connected to my home network yet because I will be going through a lot of different exercises playing with services, installing/reinstalling etc.

So how do I do a clean reinstall over an existing install of the server OS if I don't have a separate display and keyboard. Every remote solution I can find first involves booting the mini from an external optical or USB drive which requires a keyboard and display attached to the mini.

In reality I could attach them, but I'm trying to learn how to do it in a real life situation where it might not be possible.

Am I missing something?
Start the Mac Mini in Target mode. You'll need a keyboard, hold down the "t" key as it boots. 
Connect the mac mini to your MBP with a firewire cable.
Boot the MBP and hold down the option key. 
Select the  macmini as the startup disk. You should be able to install and configure the mac mini. Then just shutdown and disconnect everything. then restart the mac mini on its own.

Make sure the mini is set to connect to your wireless. So when you boot the machine on its own it connects right away. Also be sure to enable remote desktop access.

This is how I setup my macmini recently.
