Needed to replace my old NVR for the cameras and for the price of a decent NVR, I turned this machine with simply adding a 3TB NAS drive for clip backup and a $70 Blue Iris license and now have a very intelligent and powerful system for a total of about $300 bucks!!! Highly recommend for even base use. Good to put these units back to life especially considering a comparable machine in price NEW would be a base processor, windows Home vs pro, etc etc.
