This PC was in excellent condition as refurbished and it booted up right away with no problems at all. WIN 10 PRO is a plus, and it was already setup with a digital key. Its a very good machine, and it's on the small size. Not the old bulky desktops. There is 4 extra card slots. It works like a new system.Would definitely do business with them again. There was a small hiccup but the seller worked it out with me, so that was also a plus! Make sure you make a system restore in case windows crashes. This is a very fast system. Quad coreThe hookup is veru simple, if you have a older system just ove the plugs etc to this one, and it's good to go. Having a VGA out is good since all the older monitors use VGA. It runs basic games, but with the current GPU, it will lag with the heavy memory hogging games. For regular use, minus games, its very fast!!!
