I am getting into computer science and I needed a computer for a variety of tasks while not breaking the bank. You are required to gently remove the Styrofoam type bag from the graphics card area. You are also required to check and see if any cables are loose or disconnected before attempting to turn it on. There are unused cables zip tied to the yellow cable connected to the graphics card. These seem to be available for further upgrades to your PC in the future if you desire. No need to worry about them. It comes with extra cables and mounting frames. These are used for installing more hard drives if you wish. It also comes with a disc to activate your motherboard, however there is no place to insert a disc. But when I turned the PC on, it was working perfectly. The manufacture already activated it, but I believe they are required to send you the disc anyway. One more thing. When connecting a monitor, make sure you connect it to the graphics card and not the motherboard to ensure good performance. There should be a sticker on the PC showing the location of where to plug it.It is a beautiful PC. Very quiet too. I haven't used it for gaming yet but it is very smooth and downloads software at a satisfying speed. The only thing I don't like is how the RGB LED lights work. It comes with a remote instead of software like AURA SYNC. I could very easily lose the remote. But for the price I can't complain and I am very happy with it. I am going to use it for a long time.
