Is £380 good for this? https://uk.webuy.com/product.php?sku=SDESAPPMM6101A#.VQMwz4qQGnM From what I can work out its a Late 2012 model. I don't want to have to buy an expensive monitor to use it. Can I use my TV which has HDMI ports as a monitor? I only need a monitor to set it up and set up an iTunes account. What's the maximum size HDD I can fit in it? Will it work without a monitor? My intention is to put all my movies and TV episodes on to a 3TB external HDD (or internal if it's possible) and set up home sharing to stream to my Apple TV. I don't need a monitor once it's set up.
