So i've never really needed a macbook before but my friend needed some money. She sold her macbook pro 13" 2010 model to me for 400$, same 4gb ram and 250gb hdd. The speakers are broken and she told me it would cost around 70$ to repair at the speakers at the local authorized retailer. i'll pick it up later, but doing some research, it looks like i can upgrade to a 1TB hdd and 8gb ram, i know the max height is 9.5mm for the hard drive but im not sure which hard drive to get. I'd like 1TB to consolidate all my files into As for the 8GB ram, im having trouble finding 4gb sticks that are 1066mhz speed. i was thinking of buying two 4gb sticks of 1333mhz speed, i heard kingston brand is good, whichever may be compatible with the laptop The battery i plan on changing if its close to 1000 cycles, what are the battery apps to check the condition of the battery and if it needs changing? and how much would a new battery cost? im hoping nothing more than 50$ All in all im expecting to spend 400$ + 70$ speaker repair + 70$ 8GB Ram + 70$ 1 TB HDD + 50$ battery+ 40$ case/screen protector/keyboard and palm rest cover around 700$ is this a good buy? any thoughts or opinions?
