This is meant to an as complete as possible installation and configuration guide for changing your Mac mini (or any other Mac) into a full blown internet connected server to be used for all your needs at home for yourself, friends and family. You won’t need to buy OS X server license for this, everything is done using free open source software that have been tried and tested by a large community..
When you have followed all the documented steps you will end up with a secure and stable server. It can be your web, mail and more server which you can connect to the internet at home using your broadband connection or have it located in a hosting datacenter like macminicolo.net.
All steps are generously documented and all the decisions will be explained. You don’t have to install everything, where choices are possible they will be explained as well as the consequences. Good luck.
