One of my best purchases. I run this with VMwares free ESXi virtualization solution. I run my entire test lab off of this one system. Currently this runs 2 Windows 2016 servers(domain controller, IIS) and 3 Linux servers (2 HAProxy, 1 content filter)In the past i have used full sized rack mount servers to run my lab but this little beats is so powerful that it can cover my need in a fraction of the space and without any of the noise.I have this running with an M2 drive and 32GB of ram.
