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.
