HP EX475 MediaSmart Home Server
Everyone wanted to knock this product, based on Window Server when Microsoft announced it. But after a length beta process, the feedback was overwhelmingly positive. This tiny machine (I've seen it in person, trust me it's small) is quiet and sits in the corner of your room, or closet, and just does it's thing. Automated backups and media sharing are its forte and it even links up to Apple TV, iTunes, and Xbox 360. Score!
