Easy to setup and streams films (1080 at least) well.
I literally just wanted a film library to watch on my TV without having the PC on 24/7, and it's perfect for that. In a silent room you can hear the hdd sometimes but once a film is streaming you can't hear it.
I put no for is it fast but it's no slouch either and moves films from the PC (ethernet connected) to the NAS.
Not tried connecting externally as yet.
