I ordered this for a friend whose very, very old desktop PC (Windows Vista) wouldn't start-up any more. We evaluated options and he decided to try a renewed unit to save money.We saw this one and it had a decent i5 CPU, 16 gb ram, SSD, DVD and Windows 10 Pro 64 bit OS so we ordered it. Arrived in 2 two days and I went over to set it up for him. Nice small footprint. Updated Windows, personalized his desktop to be as close to his old PC as possible.and he was ready to go. We used his old HP monitor that had  DVI and VGA ports, this one had Displayport and VGA. With the newer Intel graphics in the new PC, using the VGA por, the monitor looked better than it ever had. That was a bonus. And this PC boots fast.He can have lots of windows open and it doesn't seem to slow down. We were both pleased with.the price and performance of this unit. Haven't had to call customer service yet, which is a good thing!!
