SharePoint Back-end: 16GB Ram, 4 CPU cores, 160GB HDD (SSD preferable)
SQL Server: 8GB Ram, 4 CPU cores, 160GB HDD (SSD preferable)
(Optional) OWA Server: 4GB Ram, 2 CPU cores, 160GB HDD
KanBo App server: 8GB Ram, 2 CPU cores, 160GB HDD

100x SharePoint Server 2013 Standard or higher Client Access Licenses (not applicable if SharePoint Foundation)
4x SQL Server 2016 Core (or free SQL Express)
a number of KanBo User licenses depending on number of users

User Profiles Service Application configured to import users form AD
SharePoint farm configured for apps https://technet.microsoft.com/en-us/library/fp161236%28v=office.15%29.aspx
If you want to have the feature of KanBo Email notifications: support open relay SMTP servers and servers that require authentication (http://community.kanbozone.com/topics/74-setting-up-kanbo-email-notifications-on-premise/)
If you want to have the feature of KanBo Outlook app: Requires Microsoft Exchange 2013 or higher (http://community.kanbozone.com/topics/73-kanbo-outlook-app-installation/)
Step by step KanBo installation can be found here http://community.kanbozone.com/topics/80-kanbo-on-premises-installation-sharepoint-20132016/
Please be aware that it is also possible to run all services on one or two virtual machines (1. SharePoint + SQL + KanBo; 2. Optional OWA Server)
If you have SharePoint already set up - all you need is a separate KanBo Server - all other resources can be reused and there is no need for additional hardware or software licenses.
You can also check the installation structure in the on-premises scenario in an Architect Stack Diagram.
