This PC is advertised as a business capable PC, but I'm a network engineer major, and it could not keep up with me at all. I tried replacing the built-in CPU and adding extra RAM sticks, even a GPU, but nothing helped. Also, it is NOT compatible with HDMI input. VGA & DVA connectivity only.Now that I've been trying to repurpose it into a standalone server, the power button is blinking orange and refuses to boot into Windows. Granted, I've had this PC for ~2.5 years, but had to upgrade to a Lenovo laptop a few months later. This thing is not a good device, especially if you're like me and like to tinker and use multiple operating systems.
