You could also take a look at a Technet subscription. The Professional Download-only subscription costs about GBP £250 in year 1, and about GBP 200 to renew. This gives you access to full versions of all Microsoft operatating system, server and office software. With this you can install any Microsoft operating system, and version of SQL Server, SharePoint, etc plus whatever you need from the Office stack, just so long as it is only used by you and is not for production use.
