Bought this refurbished from SkyTech USA.  It has replaced my old dinosaur office computer.  I inspected it closely upon arrival both external and internally.  The computer looks brand new all around, perfectly clean and free of any wear marks or blemishes.  Was preinstalled with Windows 10 Pro, fired up and activated without a hitch.  Came with a USB wifi adapter, very basic mouse & keyboard.  Really like the fact that is has a SSD drive instead of HDD.  Plenty of usb ports front & back, RJ-45 networking port, and an RS-232 serial port that I need for interfacing field instruments.  On board graphics are plenty clean & fast for my needs.Shipped fast & received two days after ordering.  I'm very happy with my purchase, would recommend to others.  Good value for my needs.
