i have a mbp 1,2 a1151. i am wanting to go a little faster and upgrade to mountain lion. my question is can i swap in a logic board from say a mbp 2,1 a1212, or a 3,1 a1229. buying a new mbp is not a possibility right now however i can get a logic board pretty cheap. i would imagine heatsinks would be a little different. what about other connections, screw holes, lcd connectors. if anyone has any info that would help out i appreciate it. thanks
