What are you using for bulk storage? How many external hard drives are you using? I was considering a 3TB fusion drive, but many have suggested SSD instead. I currently store quite a bit of music for streaming, lots of photos used with Lightroom, plus the other typical things. The selling point of an all in one machine to me is reducing the wires and plugs, of which I already have too many with various devices. Once you start adding in a DVD drive, USB hub, etc. (not to mention a router, modem, box for voice over internet, speakers with subwoofer, microphone and audio interface), that clean look goes away quickly .
