Let's see here...multiple hard drives, optical drive (still needed for work), SSD, TV tuner card, sound card (anyone who says they can't tell the difference between a real card and onboard is deaf), PCIe parallel port card for old laser printer, FX-8350 that requires cooling.
Sorry, mini-ITX is a no-go here.
We could create these kinds of threads for anything. For a lot of people, a $69 off-brand Android tablet is all they need. And a lot of people who are in that category have figured that out, which is why PC's don't sell as well as they used to. But if you're on OCN, you may well have computing requirements that mini-ITX doesn't meet. I wanted a PC that could assist me in my profession, and also double as an entertainment/media center, with massive storage, redundancy for important data, quality audio, and good performance. To do all of that on mini-ITX would have required the use of USB ports, adapters and external drives out the wazoo, and if you have to do that, what's the point in the first place? Build an ATX machine and be done with it.
