This computer set up flawlessly. The included WiFi dongle worked, but I replaced it with a wireless card. This improved internet connectivity tenfold. I was so pleased that I ordered another one that redirected to a different seller. I didn't notice this. Unfortunately, I never received it and my money was refunded. I subsequently ordered a different computer, ensuring the same seller, and anticipate its arrival. Tech support was not needed. I do not use this for gaming. I use it for streaming, surfing, data storage, smart home activity, and wireless surveillance monitoring.
