We have 193 movies and 259 tv shows (so 452 total items) taking up approximately 360G on our iMac. It is approximately 11 days of viewing (for 360G). The Shows were either Handbrake or bought from iTunes. Does this make sense for the amount of space they are taking up. I know that it can be all over the place, but I am trying to figure out what size new iMac to buy.
