Hi all, I've had my macbook for 2 years now and i think its time for a bit of an upgrade. I want to put more memory and a larger hard drive in her. I just need a bit of help. Memory: I am right in saying that first generation Macbooks can only take 2Gig memory (2x1 gig)? Is there much of a difference between brands? Hard drive: Can i use Sata-300 or only sata-150? Is there any size restrictions or the largest 9,5mm one i can find? Which would ye consider better, larger size or faster (7200 rather then 5400)?
