So Over the past few months I've been posting on here about possible upgrades to my 2007 white Macbook. Its the model identifier 3,1 That i purchased new in boxing week 2007. It came stock with the Core 2 Duo 2.2ghz CPU, 1gb DDr2 ram, 120Gb hard drive and OSX 10.5.8 (Leopard). Last year i had 4gb RAM put into it and a 750GB hard drive. But since im off to university this year ive decided to take it to the next step and went out and made a purchase of a new Drive for it! My first solid state Hard drive! After some tinkering around i disassembled the macbook and removed the CPU fan and heat sink off the system, cleaning the old slowly getting chunky original apple thermal residue with rubbing alcohol and applied fresh thermal compound on both the CPU and GPU. Next i cleaned out The fan replaced the HDD with the SSD installed and installed Lion. I found lion to be kinda slow and didnt much like it so i returned to snow leopard and i am a happy camper. As the system boots up in under 30 seconds and will soon be ordering a new battery for it as well as this baby still needs to make it through my years at university. LEt me know what ya think guys! LIVE ON WHITE MACBOOKS!
