Hello there, I was told that we can't buy new Jira Server installation licenses anymore. How about the "Data Center"? If we want to deploy the "Data Center" products to support 180 users on a on-premises non-clustered server, what's the recommended specs of the server hardware?

You've answered your own question here - a non-clustered server is simply a server. So you can use the recommendation for a server product straight off Atlassian's sizing pages.
It gets better - they also recommend that when you are sizing nodes in a DC cluster, you use the same numbers! So if you decided to add a couple of nodes to your single-node cluster, great, start by sizing them at around the size of the existing node!
