Beyond the basics, most of the answer depends on the load you expect on the server. Are you expecting 5 users at a time, or 5,000, or 50,000? Also, is it a simple informational site, or will there constantly be a lot of interactivity between the site and the user?

If you're not sure, and you're new to this, you might go with something like Managed.com (formerly powerdnn.com) or some other respected DNN host where they can move you between hardware levels pretty painlessly.
