Well if you proceed slowly take pictures every now and then you will be fine your worst problem might be a cable that you forgot to connect and you have to remove everything again just to connect that cable believe me i started dissassembling computers like 2 years ago and i feel pretty confortable around any computer now i have already fixed more than 10 laptops failed to fix only 3 that where completely dead and never damaged anything too important the only thing i damaged was a wireless cable and since i had some laptop antennas laying around i replaced the whole thing And yeah a like star wars but i'm more into action movies :)
