Do you have to have a sub?... that is, will you use this more for music while working, or for watching movies?
For a small, consumer-oriented musical PC speaker, I've found the Klipsch ProMedia 2.0 hard to beat. (approx. $100 retail) They're vented out the back, but still sound a lot cleaner and tighter than any computer speaker costing twice as much at Best Buy or Fry's.
But if you really want to spend $400, you might go to a music equipment store, and check out some of the powered near-field monitors by M-Audio and similar manufacturers.
