I've also been thinking of doing this for years, ever since I first starting reading about mini-itx motherboard projects.
And with the Keyrar available it makes interfacing the original Amiga keyboard, and also providing working Amiga joystick ports, really easy. Would definitely make a great emulation PC. I actually have a spare A1200 and A600 cases, and a spare A600 keyboard, so that is some way towards it.
The biggest question though is which motherboard to use as there are now so many available. I think it would need a bit of power, so a desktop CPU like a Core2Duo or if possible an i3, would be much preferred to an Atom or similar network CPU.
I would take it further than the A1200 project you linked to though. I would add a slot loading DVD-RW and look into the possibility of utilising the floppy drive location for a floppy drive, connected to either a CatWeasel or a KryoFlux. There are some mini-ITX board with a single PCI slow, and 90 degree PCI adapters so a CatWeasel could be mounted next to the motherboard in the case to make it fit.

Except if you have a spare case and keyboard, but no Amiga motherboard, then I think it is perfectly acceptable. But, people who actually rip out the guts of a working Amiga to do this need to just be shot!

I was thinking about it.... i do have a spare case and keyboard...
you could use a micro-atx or a laptop m.board....
with a laptop board, you can use it's own power supply, but what about micro-atx, will you put a small one inside, or use an external PSU ?
