I think this must be the A06 rite of passage: feeling this is easy, seeing the lcd frame bend and becoming overly cautious, get through everything with the instructions at your side but struggle aligning the top case, realise the heatsink isn’t in the instructions, open it back up to apply the heatsink, struggle to align the top, open it back up because you just noticed when you applied the heatsink you dropped the power button/one/both side panel(s), realise you are now expert at getting the top on, profit
