The computer freezes frequently and must be rebooted every ten minutes. I couldn't make it through the setup without two failures that locked up the computer. I never added any software, this is how it came. The tower had damage to the rear,  metal was bent and deformed. I had originally planned to install a video card, but the deformation made this difficult if not impossible. The access panel would not latch to secure, it would just fall open. Some units might be ok, but the one I received was a very shabby product in both form and function.
