Hi, I need to buy some pieces to repair two 13.3" MBP's. These computers are from early 2011, the ones that came with 4 GB of RAM and a 320 GB hard disc. The pieces I need are the following: One WiFi Card One Hard Disc; 320 GB, 500 GB, or any other size! One mother board One battery One keyboard These pieces will be used to repair two other 13" MBP's, as I mentioned. Another option is to buy a similar computer to source the pieces from. I would very much appreciate if you could please tell me where I could buy these pieces (or a computer) and perhaps to give me an idea of the prices that I should pay for it. Thank you, kind regards, igmolinav : ) !!!
