I don't thing is a good idea to buy a windows client to work as a server to host DBA/EVO
You are going to have issues. You should buy a server. DBA/EVO is a server side ERP
Also, if you call a mayor dealer or Microsoft itself they will literally force you to buy the lattes an greatest Windows Server
No need. You can go to E-Bay or Amazon and buy an older Windows OS Server. It will work just fine.
It must be a compatible version for your Pervasive (Zen) Version
Have fun,
