I'm going to have to see if I can find pics of the PC I made for an ex when mini ITX boards first became popular. She had an "olde fashioned" office/library at home and didn't like how the plastic and metal cases looked in there. The PC looked like a walnut humidor and I also recased the monitor to look like a large picture frame.
As cool as that vid was I'd just use an off the shelf or printed plastic enclosure for that sort of use.
