Again, they will work but they are more expensive and much lower spec/lower end machines than the refurbished ones I linked on Newegg... If you don't like those, look at the other refurbs on Newegg - They have tonnes of ex-business systems with good specs for the same price as the really low end laptops you keep linking.
I know it's his first computer but I don't see why it has to be a really low end and slow machine when you could get him something much more powerful for the same price that will last him longer. Surely you don't want to be teaching him how to use a computer that will be frustratingly slow to use.
