Bought this to replace a laptop that I was not using as a laptop. It was my everyday computer and about 12 years old. I work in the IT industry and was going to build a tower, but saw this and had to give it a try. Delivered in great packing. Came with Windows 10. Only one update necessary upon arrival. Now down to the critique... Only complaint is the 8 GB of RAM. So, I added 24 GB for about $100 and this machine is as perfect as I could ask for. Runs quiet, very fast, and so far, very dependable. I would highly recommend this to anyone who is looking for a good graphics or gaming PC that only requires a few sticks of RAM to make perfect. Can upgrade the video card and processor if needed, but for what I require, this is more than enough. Adobe Photo Shop and Diablo III function great on this machine. My wife likes the LED fans, which means I may have to buy one for her as well, and would have no regrets in doing so.
