I have been searching thread for same topic, but couldn't find the exact needs. I'm looking to keep Apple products as the main solution, but understand that others may be needed to complete system. What I have: iMac - Main computer with the majority of my data (1TB - Movies/Music/TV) Mac Mini - Secondary computer used for some additional music ATV 1 - Living room ATV 2 - Bedroom Airport Extreme - I don't think I'm using this to its full capability Airport Express - Hook up speakers to play music around house/outside iPad - Would like to incorporate more (use the Remote App) iPhone - Would like to incorporate more (use the Remote App) My main iMac is slowing down due to the data on the computer. I want to set up a network hard drive that can be accessed by all my apple tvs at any time. I want to buy a larger external hd (2-4TB) to hold me over for the foreseeable future. Looking for ease of use with streaming music and movies. What would be the best set up considering the resources I already have (with the exception of new external hard drive)? If you know a thread that has tackled this issue, please feel free to point me in that direction.
