you simply want something for him to do homework and a few personal items [i.e., video/music]. If that is correct, I would simply contact a local reputable PC refurbisher in your area and have them build you one.

That way you can specify the precise programs you want [e.g., Word or WordPerfect, whatever musical programs, whatever photo programs, etc.] and NOT have a machine packed with BLOATWARE.

Since the guy is local, you would probably also get better technical support.
