Extra computer power

Hey, guys how's going? Yesterday I found a extra computer power in my cupbroad, 350W and hopefully it can be used in our project. Otherwise, I seacrhed the Philips Webcam online, it's quite expensive in au, but in us is ok~However, do we have to use the exactly same Webcam? can we try some others frist? and also our report it's due on Fri. I think my part will focus on games which we're gonna use in our project. Is that all right for u guys? pzl send me E-mail if anything I can help....thanks
