This is an impressive compact PC that offers very good performance in a small package. It comes with Windows 10 Pro pre-installed. There is little extraneous software installed on this computer, which is appreciated. Windows was already activated on the computer - I chose to do a Windows reset which went without a hitch. The housing is made of aluminum, and looks good. It has a non-distracting single, small red LED to indicate power. On the front are a bevy of ports - 4 USB-A, 1 USB-C, headphone and microphone jack. On the back are two more USB-A ports, ethernet, Display port and HDMI. The power supply has a cord that plugs into wall, making it easier to find space.The computer has impressive specifications and doesn’t disappoint when it comes to performance. It more than meets my needs - a compact computer that doesn’t take a lot of space. It certainly bests my previous compact desktop - media applications run well. The built in graphics are good enough for day to day work - high definition streaming video plays smoothly - but likely not enough for hard core gamers. The computer is very quiet unless it is running highly demanding tasks, where the fan becomes more noticeable.I’m really pleased with this computer overall. It makes for a nice desktop with plenty of ports and good specifications. It really doesn’t need to be upgraded further. It has a nice combination of price, performance and size.
