What is the best way to handle files for a small office?

Question

I'm currently working at a small web development company, we mostly do campaign sites and other promotional stuff. For our first year we've been using a "server" for sharing project files, a plain windows machine with a network share. But this isn't exactly future proof.

SVN is great for code (it's what we use now), but I want to have the comfort of versioning (or atleast some form of syncing) for all or most of our files.

What I essentially want is something that does what subversion does for code, but for our documents/psd/pdf files.

I realize subversion handles binary files too, but I feel it might be a bit overkill for our purposes. It doesn't necessarily need all the bells and whistles of a full version control system, but something that that removes the need for incremental naming (Notes_1.23.doc) and lessens the chance of overwriting something by mistake.

It also needs to be multiplatform, handle large files (100 mb+) and be usable by somewhat non technical people.

SVN is great for binaries, too. If you're afraid you can't compare revisions, I can tell you that it is possible for Word docs, using Tortoise.
But I do not know, what you mean with "expanding the versioning". SVN is no document management system.

Edit:

but I feel it might be a bit overkill for our purposes

If you are already using SVN and it fulfils your purposes, why bother with a second system?
