Do you want/need to test the fully featured Microsoft SQL Server 2014 Enterprise edition but you don't have access to MSDN?
All is not lost! For 60$ USD, you can buy the developer edition which is really the Enterprise edition. It's licensed for use as a development and test system, not as a production server, and is an ideal choice for people who build and test database applications.
You can get it from http://www.microsoftstore.com/store/msusa/en_US/pdp/productID.298540400
