I ordered this to install Batocera on. I asked if the PC came with one stick of 8GB and not 2 sticks of 4gb. They responded by saying that it would come with one stick of 8gb ram. When I got it, it did not have an 8gb ram but 2 4gb ram. So instead of adding one stick I had to buy two sticks of ram in order to get 16gb. After examining the ram I decided to open up the CPU heatsink to see if the paste had been replaced. Yes it was replaced but twhatever was used was subpar and was a bronze color....obviously something cheap because it was so easy to wipe off. I replaced it with some artic thermal paste. Also the cord they gave me was defective and I had to borrow my laptop charger in order to use it. I couldn't contact them to ask for a working power cord otherwise they would've asked me to return the whole unit after I had purchased parts to upgrade the computer.
