This tower was delivered today. One of the RAMs wasn’t locked in properly so naturally it moved all over the place inside the tower during shipping. I guessed this the moment I unpacked the machine but confirmed it when I had to open the side panel to verify . Of course the 4GB RAM was just chilling at the bottom of the tower. One of the microchips on the RAM had already fallen off! I am requesting a replacement 4GB RAM since the machine seems to work fine with the remaining 12GB. Will review properly once customer service takes care of me
