Hi; Couple of questions ref upgrading my old Macbook 13 Inch White Mid 2007 model (redundant since I bout my Late 2008 Macbook Pro). 1. The Hard Drive is trashed so could I replace it with this one - http://www.microdirect.co.uk/Home/Product/56423/Hitachi-160GB-CinemaStar-Z5K320-5400RPM--hard 2. I recently upgraded my Macbook Pro could I use the 2GB RAM that I took out and fit it in my 13 Macbook White. According to Apple Support they are both DDR2 667Mhz? 3. Will it run Snow Leopard OK? 4. I think the DVD Drive is also bust - can't remember, where can I get a replacement? 4. Is it worth upgrading it?
