from the looks of the tear down videos. most of these models look fairly straight forward.
if you do decide to tackle this. a few tips
take your time. if something isnt coming apart, theres usually a reason. maybe you missed a screw or theres a tab to lift \ remove.
if you find yourself getting frustrated. take a short break. get something to snack on and come back to it. i cant tell you how many times this will save you a broken component.
document your disassembly. take pictures. or take a sheet of paper and place the screws on the paper where you removed them. it is pretty defeating when you get it back together only to find a screw or part laying on your desk lol.
be careful where youre poking around when you remove the heatsink. ive tried prying up on one near the CPU and popped a capacitor off. thankfully it wasnt a cap that was needed to run and didnt have to, but did resolder it back in place. i guess this kinda goes back to taking your time :)
any questions post up!
