I apologize in advance if this is not an SF question, but I'm thinking it's in the gray.

Are there any good Open Source or atleast fair priced "intranet" project portals where you can have a dashboard, view your tasks as well as your employee's and co-workers tasks so you can see what your team(s) are working on.

I'm looking for something that is not cumbersome to manage, has a clean UI/Dashboard, etc. etc.
