What can I say, I ordered one from Computer World Ent. and it arrived in very good condition. It IS a used system, NOT new so it usually will have a few dings and scratches. The inside looked like it was brand new, It isn't, But it was spotless, They did an excellent job cleaning it. It booted up surprisingly fast, Quicker than my Ryzen 3200. It originally had Windows 7, But upgraded to windows 10 Pro, Says in settings it is activated. Bought this to make a mini gaming system for my sister-in-law, I added 8 more gigs of RAM, Replaced 2 sticks so now it has 12 gigs, Also added a low profile Gigabyte Nvidia GTX 1650, Fit perfectly with low profile bracket, And works just fine with the stock 240W power supply. I am going to add another fan to the outside of the case, Have to cut a hole for it, But there is a open connector on the motherboard for it and it will help exponentially with the cooling since it is a  SFF computer without a case fan. All in all, An awesome little computer for the price, Just make sure to buy it from a reputable company, Read their reviews, Computer World Ent. has some good reviews, And the computer I got was in good shape and spotless on the inside, Your mileage may vary, But I wouldn't hesitate to buy another from them.
