So, on their product website for the n4020 it states in their QA section:1. What is the maximum memory that can be installed?The RAM of this COOFUN Mini PC can be expanded up to 32GB (16GB*2). It is recommended to use Kingston memory sticks.This is incorrect, the memory is onboard and there are zero slots to add anymore ram. I contacted tech support via ticket, waited 3 weeks with no response. I also tried calling during their open business hours and the phone just rings forever. Overall, I do like the product, but I purchased this knowing I could upgrade its ram in the future, which I cannot.
