Hi sumstuf,
In addition to some great advice, if there are only 10 computers in your network and file server is the main concern, why not use a NAS starting for about < $150 for a terabayte, there's no need for a Server. I use this for work and home. I would advice to get the
gigabit NAS. Have a read on one of
my Articles here about NAS. You may buy a disk less configured RAID (for better performance) or NAS with disk -
a few selections here from Buffalo and it's very easy to setup, just plug it in to your Switch or a Router then run the installation CD from one of your computers, it will pick up the IP Address of your NAS, then create the same Users/Passwords that you have already have on all 10 computers. A NAS can be used as a Print and FTP Servers as well.
The
SBS2011 is a great Windows Server however, you will need someone in your company that knows how to administer Windows 2008 Server R2, the Roles, Apps, it's configurations and how to manage the AD Users and Computers. SBS Essentials is a great addition to SBS family, it supports up to 25 Users. I'm a fan of SBS family.
Other solutions that you might consider is a
Cloud Solution, work any time and anywhere around the world, no need for a Server to run, just a computer and a working internet connection. Google Apps is around $5 per User/Month including synching all emails in your Smart Phones/Blackberry. The
Basic Google Apps package is Free for up to 10 Users. Office 365 is around $6 per User/Month. Have a read in
this Article for more info.
Hope this helps.
