This thing has been amazing for me so far. I have a TechNet subscription so I was able to overlook the fact that it comes without an OS, and I'm currently running Windows 2016 Server with VMWare Workstation for all my lab environment needs. I can run at least 4 fully loaded servers without worrying about running out of RAM or system slowness. It's quiet, boots fast, and the hardware is good. The only minor complaint I have is the BIOS is a little hard to navigate, but I was able to select all the settings I needed.
