The problem of physically fitting / screwing / securing the AIO-mobo inside the tower can probably be overcome with persistence and ingenuity.
The greater problem is more likely to be:
- What about all the electrical connections?
- Especially getting a connection from the board [which is designed to run an internal monitor] to an external monitor?
It's a very interesting question, and I would like to see this thread populated with more responses.
