Q: I currently own an iMac, MacBook Pro x 3, Mini Mac, and Mac Server, and I need help to make the units link together

I currently have the following Apple Products

1     Mini Mac

1     Mini Mac Server

3     MacBook Pro (2-13, 1-15)

3     Time Capules

3     iPads

5     iphones

1     AppleTV

(What can I say, I am an Apple Loyalist)

I need help to try and "link" them to a server type setting, but not sure to go about it. 

Can anyone out there offer suggestions?
