I am an IT technician in a high school with around 1600 students 250 staff and 800+ client computers mostly running Windows 7. Our team is composed of three members. My boss seems content with a network that works (just about) not necessarily a productive well maintained network that is easy to run and maintain. I'm still fairly early on in my I.T. career so I'm not up to speed on all the different endpoint management solutions that are available.

I'm looking for a better way to manage clients (deploy software, track changes, inventory etc) I like the look of SCCM 2012's features but the case studies seem to be aimed at large multi-site infrastructural rather than a single mid sized site.

Is SCCM suitable for a mid sized single site or is it aimed at much larger corporations? How can I determine whether or not an endpoint management solution like SCCM is a good fit for our organization?

EDIT: Thanks for all the help I'll take a look at SCE and SCCM and get some proposals drawn up to take to my boss/deputy head
