Hi, I know there are loads of threads on this already but i want to get the opinions for my situation. At the moment i have a macbook pro with my iTunes library on it, an iPhone and an Apple TV (i also have a base station and external hard drive in cupboard doing nothing) What i want to do is be able to listen to my iTunes on apple tv and airport express linked to stereo (if and when i buy one) but without having to have my macbook on all the time messing the battery up. However i want something that i don't have to go and turn on to use i can just control from my phone. I see a lot of people use a mac mini to do this. Is this the most cost effective way and if so what is the lowest spec mac mini i could do it on? Also can i keep my itunes folder on my mac too i do i just do home sharing on the mini? I'm not to fussed about streaming movies as i do this off ice films on the apple tv. I keep meaning to build my own movie collection but i think by the time I've spent time build an HD collection we will be onto super HD. Anway if i do decide to build a collection i can plug my hard drive into my base station and access the files through xbmc on apple tv so that is not an issue.
