I am building an ERP solution using Microsoft .net and SQL server 2012. I would expect about 20-30 users and my client would like to buy his own server rather than go with a cloud based server.
Given the performance needs of a small enterprise with about 5 concurrent users using a web application (not directly accessing the server) which is the cheapest or the lowest configuration server that I could recommend.
I am considering if hot swappable components would be essential as the server is used primarily for an ERP and can be taken down if there is a component failure.
I was suggested a Dell Power Edge T20 Server, which seems to fit the client's budget, but not sure if there are better options for that sort of a budget.
