Unpacked the unit, made the connections and it powered up first time, ran through the Windows initialization, and I was off and gaming. It took some time to download my first game, Dishonored 2, and it ran beautifully. I built my last PC and kept it running for 10 years, but it finally gave up. Looking into building a new one, this system seems to have quite a lot of technology (memory, CPU, graphics) for a decent price. Similar systems from DELL, HP, and others all seemed higher for the same equipment. I always had issues with my last PC overheating, but this one keeps nice and cool and makes just a small amount of noise. I thought the circle lights would be distracting, but unless they are directly in front of you, I like the way it looks, like it's working away as the lights spin. A remote is included to change the lighting pattern/color or to turn them off. On the whole, I'm very happy with this purchase. After a month no issues to report.
