I am sure similiar questions have been asked a million times but with technology and equipment names morphing so rapidly i am finding it really hard to translate previous advice to current model names, so please bear with me.
Am looking to set up an external hard drive/backup for my two wireless laptops. I would like to store all my music and especially photographs/videos and documents as a backup on this and "stream" it to an output in another room.(BTW i need to get a decent set of speakers/hi-fi as well- need FM radio and mp3 playback on it)
I do have a wireless router but would want to buy all the other kit within £400-500 if possible.
Am also about to buy an HDTV (not part of this budget though)- does it need to be DNLA or whatever to talk to this setup or is that not important?
My understnding is i would need the following
1. an NAS/ external hard drive- any suggestions
2. something to stream music- like logitech squeezebox boom maybe
3. decent speakers/player
BTW i am in belfast so have relatively limited choice of music stores etc.
I am asking the impossible or .....Would realllllly appreciate any advice/thoughts.
