    Great Home Server

    I recently purchased this server. It is an investment but if you need a home server to store files, movies, music, etc., this is a solid option. The unit comes with 4 pre-loaded hard drives and is fairly easy to set up for non-computer savvy people. Once set up, you can easily access your data via your computing devices and/or streaming apps. Additionally, you can access files remotely via its Cloud functionality. It has worked smoothly and I haven't had any issues to date.
