Build a clustering computer using multiple LattePanda-mu (N305)

What would be the best way to build a clustering computer using lattePanda Mu? 
Should I use a career board for each LattePanda Mu module and clustering with Ethernet?  In that case, should I use power adapter for each career or could be a larger PSU to provide a power?  
Or is there any clustering career board for 5 or 10 of  Latter Panda Mu? 
Any suggestion?
