Add a new node to a 2012 cluster

My company currently has a 2 node cluster (Windows 2012), and we are looking to buy a third machine and adding this as a new node.

According to Microsoft, the new node should be identical to the other 2 nodes in terms of hardware, firmware etc, but that simply won't happen because of how quickly hardware changes and the cluster was setup a couple of years ago.

So, my question, has anybody added a new node to a cluster, with differing hardware? Has it caused any issues or did you encounter any issues.

Many thanks in advance

You can add a 3rd node with out issue.  Exactly matching hardware requirements (in my experience) is usually tied to the initial build of the minimum 2 node cluster.

I have had to update a production cluster (win2012) with minimal downtime.  Went from older 2010 HW to a current HW setup.  Built new node with same OS, added WFC services, added the new node to cluster, migrated roles from an old node, then ejected old node from cluster.  Did this for the 2nd node.  Cluster HW upgraded, no issues.

So adding a 3rd node with newer HW should be just as easy.  I would recommend that the new HW should as capable as the existing nodes, if not more powerful.
