I finally got my HP MediaSmart Server EX475 (the one with two drives). It was very easy to setup- you pretty just plug it into the AC and plug the ethernet cable to it & the other end to your switch. It only took about half an hour or so to have it up and running completely. The Photo sharing is pretty cool and I like the ITunes server as well. This is a cool home NAS server. You can even add more software to it like Caller ID software. I'd give it a rating of 5 out of 5 stars.
