Eddie wants to buy a new Windows PC. What should he get? Leo says that he recommends a new Dell Tower. But HP and Lenovo work too. How much RAM? Well, for general stuff, 16GB of RAM will keep him comfortable. Get an Intel 8th Gen i5 processor, or even an AMD processor (they're cheaper).
But for what Eddie is doing, a Chromebook or Chromebox would probably be a better buy. Windows machines are really overkill now.
