Quick question for all you guys. I have the opportunity through work of acquring a 360 Arcade system for free. my question for all of you is: would it be worth my while to pick up the system for free and just buy one of the xbox 360 hard drives? also....other question: i have heard that there is a SLIGHT difference between the arcade and regular version (elite included) of the 360 and that the faceplate can't be changed. Anyone know if there is any truth to this?
