Computer Speakers Under $200?

Hi everyone, I'm pretty new to this forum and am trying to build the best 2.1 setup for my computer possible. Currently I was planning to use a pair of Cambridge Soundworks Newton M50's and a Cambridge Soundworks Basscube 851, which I could get for a total of around $175. Should I switch out any of those items or just what are your guys' general thoughts? I'll take anything, even flames :D
