It’s not hard to pry open…. pop off the top section at the corners. Then pop off the lower two sections at the corners. It’s just held in by clips. It comes off pretty easily (although I did crack one side of the unit by pulling too hard… so be careful of that… but that was before I popped it off easier at the corners.
I opened mine to add more thermal paste to the CPU. It was generating too much heat and the fan got really loud… now, it’s relatively quiet.
But yes, I couldn’t find the RAM to replace because it is soldered on. I do plan on swapping out the mSATA board in the future though… there’s a slot in mine for the LTE unit… so I need to research that one to see if I can find one to put in here.
