But I'm assuming in that setup you have a VGA-capable monitor on a shelf somewhere; not everyone does, of course.
In the video I mention the all-in cost, accounting for the monitor, keyboard, mouse, power adapters, etc.
This isn't a practical setup by any means, but at least you wind up with a neat couple bits of hardware that could be repurposed once you get bored of it!
The old Macs really were the perfect form factor for a compact desktop computer—you saw them in every bedroom in every 1990s sitcom.
Are there any good options these days that are smaller than a 24" all-in-one?
You’re of course looking at all laptop parts, but the form factor would be part of the appeal. Then again, an iPad dock would also probably cover this form factor for about the same cost.

I dont want to belittle the authors work, but I would call this "building custom hardware for a pico-Mac project."
