I 100% dig afterstep. It doesn't come with any 'file managers'. But, its utterly pretty.
Can't beat the simplisity of it. Makes you feel like you have more desktop space.
And, the Wharf rocks.
yeah, I'm drunk right now, but afterstep is my favorite window manager by far.
get it at
afterstep.org There is even an osx .dmg avaliable!
