Hey VirtualLarry, this is Rob L'Heureux, one of the Intel engineers responsible for Thin Mini-ITX. I've been tracking Thin Mini-ITX at least here in the US to get a sense of availability. While I'm mostly focused on the AIO chassis, I understand the appeal to HTPC as well. The Akasa Euler is incredibly creative, and I'm always interested in seeing how people are adopting and tinkering with the tech. For that matter, here are some of the other ones I've seen for sale in the US. I can't speak to specifics of any of the below, as I have not spent much time with them. However, my understanding is that the chassis are designed for use with our DH61AG or DQ77KB board, though those are also totally interoperable with the Gigabyte GA-H77TN and GA-B75TN boards.
To that end, I know the
Lian Li PC-Q05B is offered through NewEgg. The
Assassin HTPC Blog reviewed this too with some good pictures.
NewEgg also has the
Silverstone PT12B.
Lastly, there are a number of vendors selling the
In-Win K1 on Amazon.
