Insert Case Id on related child record's case lookup field

I am looking for help on a trigger for the case object.
I have three objects Case, Account and a custom object Site_Partner__c

I need help with a trigger or pex class that performs like this:
The Account object has related records from the Site_Partner__c which has a account lokup field Site__c

I need the functionality to perform that when a case record is created the trigger/class finds the Site_Partner__c records associated with the account on the case record and assigns the case ID to the Case___c lookup field on the Site_Partner__c record. I'm just not sure what the best practices solution to this requirement i.e. Trigger, Apex Class or Process builder.
