I'm not a big fan of Gateways. Lots of hardware failures in my experience. It would be better if the hard drive was 7,200 rpm instead of 5,400. There's always going to be something that's not quite ideal on deals like this. For internet only, it should be fine. See about a warranty.
Gateway isn't my first brand choice. However, for what it's worth, I've had extensive experience with them over the years and never once had a problem.
