Yeah I wasn't sure if other ram would work as the frequency was a lot higher, I did hear somewhere that it'll just reduce the speed but I wasn't too sure about it but since you're confirming it, I agree with regards to choosing cheaper ram :D
The Intel CPU cooler is good yes, but researching into it, buying a separate CPU cooler is better than the initial intel cooler.
As for the SSD, I guess I could go for a cheaper SSD.. I never really noticed that I could get the same capacity for cheaper. Thanks for the advice!! :D
