Peter - With the new squeezebox duo a computer does not have to be on. Don't think that's the case with SB3. You should to check with slim devices. You should also ask them if they recommend particular NAS drives. The Duo is brand new so they may not have much of a track record yet.
But Sonos, who has had the capability from the beginning has a pretty extensive list on their site of known compatibility issues with NAS drives. That's not to scare you off, I think NAS is THE way to go. But they aren't all the same so a little research before you buy is good.
