definitely go to Kreg's website and download their plan for an in-built cabinet with slide-out router bit drawers.  Their dimensions are spot on and it's a great weekend project.  Otherwise the fence dust collector alone will only capture 20-30% of the dust from what I can tell.  You need to box this thing in.  It's easy (and kinda fun) to do though.  The table itself is built like a tank.  The fence is in many pieces as is the table, so give yourself a few hours to get it all buttoned up.  You'll love this thing.  Lots of room to work with and very versatile.
