I will humor you - try
this for a change.
Now I don't know if this exact model has an input, but I've seen some from the same series that did. A friend of mine (also student) got one of these. I was pleasantly surprised with the sound - of course, considering the price. Shop around - I've seen some models (some with inputs for an external source) at Sears, for instance. There are many units sharing this design with orange lights and MDF boxes, and the more expensive ones ~$300 sound decent (again, for the money). Better than most computer speakers, but I repeat, for this price, don't expect any miracles.
If you want to stick with PC gear, Klipsch makes some reasonable sounding sat/sub combos (seen@CompUSA).
