As others have suggested, you can hang a HD off the back of a streamer to access your ripped music. Another approach, if you have wifi (And who doesn't anymore?) is to hang your HD off the back of your router. Then you can have your streamer "find" your files that way.
An advantage to this is that you can rip CDs and copy them to the HD via wifi and keep your library up to date. Additionally by using this method your files will be available to any other devices on your network.
Happy listening.
