Minecraft Server Computer Requirements

Any minecraft players here?

My nephew plays, and I'm thinking of building him a computer. I want as cheap as possible, but want it to play the game flawlessly. Is this overkill? What would you recommend? (Canadian pricing) Note, he'll also be using the computer as a server
