Hey guys...I just picked up my first Mac computer. I got a A1226 (MA895LL) from a friend last night. It's in great condition and works very well. I do want to upgrade the Hard drive to at least 750gb. I was looking at the Western Digital Scorpio Black 750gb 7200RPM and 16MB cache. Would this drive work in my 2007 Macbook Pro? If not do I need to drop down to a 5400RPM 8MB cache? What would be your recommendation on this or any other hard drives. I also want to upgrade the RAM. It has 2GB now but thinking should go to 2 x 2GB to make a total of 4gb. Any other suggestions would be appreciated!
