Budget gaming rig under 400. For the price, I don't see this getting much better. Obviously you can add an SSD, but that is just stuff to make general day to day experiences better, and he can do that as he gets more money. I got it as close as I could, I'm sure there are more cuts I could find, but alas, this is where I'm at. He already said he's okay with the price at 15 dollars over lol.
