I had (and still have) an aging but still fully functioning Mid 2011 21.5in iMac for daily use. It has become more problematic in recent times so I wanted to be prepared with a new Mac. This decision was before the new iMac and Mac Mini release (either one I would be happy enough with). So, I started connecting the dots. I could build a computer, noob, huge learning curve. I love to tinker and this is right up my alley. Cheaper and better performance with future upgrades. It all made sense, so I went with the build. End result is awesome. I learned a lot and had a so much fun (and frustration) along the way.
