Not sure if you already made a purchase or not, but I just received the Edifier e3350 and am very happy with them.
I was at the CES show in Las Vegas a couple weeks ago, and I was keeping an eye out for some new computer speakers. I stumbled into the Edifier booth, not knowing anything about them, and was impressed with most of their speakers. I expected them to be more expensive after seeing them at the show, but I got them on Amazon for only $70.
The e3350s sound pretty clean, the bass is not overpowering, if that is what you are looking for, but it is definitely full enough for music and movies on my computer. I have them hooked to my iMac as well. The Sub is a nice size also, kind of a rounded pyramid shape, about a foot around. I liked the sound of it better on the floor than on my desk, so that is where I have it. I got the black ones, they do have different colors if you want.
Anyway, let me know if you want some more info on them.
