If I recall, Monoman was using his M3's as computer speakers. Not sure how often he checks in though. He seemed happy with them. He was using a Sonic Impact T-amp with good results. I have M3's as mains right now in my HT and they are amazing little speakers and certainly don't need a sub for music.
