Hello, all. I was wondering if using an iMac as my media server and Home Computer at the same time would be smart, worth the money, energy efficient, and if this would have a reasonably long lifespan if left on 24/7. My plan is to have the iMac connected to my AirPort extreme router with home sharing enabled as well as a way for my MacBook (and possibly Mac Mini at work) to access iTunes and all of the files remotely when I'm not at home. I would want a thunderbolt hard drive with a very large capacity attached which would store my thousands of movies and songs. I would want these to be available to be streamed from anywhere on my MacBook/iPhone/iPad Mini as long as I had an internet connection. Additionally, I would want an Apple TV in a couple of different rooms to be able to have access to the content. On top of all of that, I would be syncing my iPad and iPhone with the computer. I take a lot of pictures on my iPhone, so I would be dumping all of my photos into iPhoto on the iMac's thunderbolt hard drive to clear up space on my iPhone. In addition to that, I also am a musician that records little demos in garage band and bigger projects in Logic Pro and there is also the occasional video editing done in iMovie (or larger projects in Final Cut Pro). So this machine would need to be able to take quite a beating in terms of CPU and RAM usage without overheating or lagging. I also am a blogger and web designer and would be doing all of my photoshop and coding work on here. I am an IT student in college and would be doing other coding from here as well. My questions are: 1.) Is it possible to do all of this? Can I have my iMac on 24/7, automatically woken up when accessed from the network, and safely available for remote access? 2.) Would leaving it on 24/7 consume an excessive amount of power? 3.) Would it overheat since it would be doing A LOT of different tasks at the same time? I build gaming PCs too and am used to liquid CPU cooling and have never owned an iMac, Mac Mini, or Mac Pro. Only MacBooks which I don't abuse too often. 4.) If this all worked out, how long would my iMac's projected lifespan be? I would be spending a lot so I would hope for a Machine that would not die on me too soon. I love the design of the all in one iMac and cannot get myself to stop toying around with them at my nearby Apple Store. I currently have a powerful Hackintosh built, but the ease of use and the full Mac OS X experience just isn't there. I would love to save up for a nice iMac if this is possible. Thank you.
