Selling my Logitech X-540 5.1 surround speaker system: http://www.amazon.com/Logitech-Surround-Speaker-System-Subwoofer/dp/B000JJM8XE They don't need a receiver or amp, just plug and play straight into a PC or Xbox console.

Comes in box with all accessories. Asking price is $90. Cash only. I'm in Sunnyvale, but if you're serious about buying, I can meet you on campus.
