I agree with abs0lut3. Actually, I've used klipsch speakers and the f2304 a lot so I can give a pretty good opinion on this. While the speakers on the f2304 really are not that shabby, klipsch will completely blow it out of the water. I guess if you really don't mind lacking the strong bass of the klipsch the f2304 will be decent, but otherwise stick to them.
I'd also like to ask if you've considered the dell 2405fpw yet. After using both a lot I can conclude that there is hardly any difference in quality between the two. The dell would take up a lot less space than the f2304. And of course, its very cheap after you chuck on the coupons.
