I have to replace the bottom case of my peryn 2.4ghz macbook pro. I was wondering if anyone bought from usedmac.com and if this model would fit my computer? I will just order this part and go to my apple university shop where a friend of mine works there as a techy and he can change the bottom case. http://www.usedmac.com/catalog/prod...=1912&osCsid=b7070111dadc7aed5adf48752dfd3563 Do you think that's a good deal? do I need more cables or I just can use the one on my current bottom case? It is urgent to change my bottom case, it's ripping apart. Thank you very much *** As anyone bought from appleparts.com? They list the bottom case at $53!
