small business server OS

would windows 7 professional be enough as an OS for a small business server?

server mainly for:

1. file backup
2. file sharing
3. printer connection
4. simple website hosting

Others may not agree, but I'm always in the mindset of using the proper tool for the job. It sounds like Server 2012 Essentials would do the job nicely.

As for website hosting, given how cheap 3rd party hosting plans are, I wouldn't consider running one inside my network anymore.

it seems that purchasing Server 2012 Essentials would almost equal to the cost of building the server itself =/


would windows 7 professional be up for the tasks listed?
