We're in the process of having our house renovted and extended and part of the project is to install the Control4 smart home automation system; part of this install will include the addition of an "AV hub" in a rack in the loft space that will serve the whole house. I've been using Plex Media Server with great success over for the last few years by streaming direct from the various iMacs I've had in that time to our smart TVs, but have decided that I'd really like to install a Mac mini in the rack with the addition of a bluetooth extender so that I can use the mini for both Plex and as a normal desktop system; albeit remotely, via the TV. I've been researching my options over the last couple of days and initially came to the conclusion that I needed a Core i7 2.6 GHz because I didn't like the idea of not being able to upgrade the hardware with the newer models. Then I saw the prices! Even if I was prepared to purchase the ever so slightly lower spec Core i7 2.3 GHz I'd still be looking at paying as much as 75% of the price of a brand new mini with AppleCare. Am I mad for considering paying more for an older model that either is or is going out of warranty just because I can upgrade the RAM and HDD?
