You can save that $137 for WinXP Home if you know where to find it. DVD Rom / burner are necessary if you plan on ripping your own DVDs, or making your own home DVDs, which I do. Then, the 120GB should be bumped up to 160GB, at least.
Portwineboy, the MB/CPU combo will run you $250+, you might as well get this:

My brother in law bought one and has been working great. I'd recommend you use Sysoft Sandra and run burn in test for at least 24 hrs. It has a 3 month warranty so you want to break it, break it before the warranty is up.
