I have moved all peripherals using my front USB to the back and so far have not encountered any problems. I did have one freeze, but it was different than all the previous ones. This time everything stopped working (no ctrl + alt + del, unrepsosive windows key, commands, etc.), but unlike previous freezes, I could actually move my cursor and hear game sound. Then my cursor stopped moving, but I could still hear game sound. So I won't chalk it up to the same kind of freeze, and hopefully it won't happen again. I'll update in a couple of weeks or so, or if the same freeze happens again before then.
