Yes, I have space requirements. But not a cabinet. I have wall mounted shelves next to my wall mounted TV that are 12"(30cm) deep. They look something like this.
I was hoping to keep the depth around 10"(25cm) because of cable connections in the back.
I've about decided to stay with the Lazer3D CG7 Cravo but wait on either a low profile Navi or go with a Renoir APU. But supposedly Lazer3D is working on CG10 Cravo out later this year. Might see what that looks like.
Can take any standard sized ATX PSU. My SFF is a similar but older model, and while boxy, it fits into carry on luggage (I take it to Japan with me) appropriate for air travel. Of course, airport security aren't used to dealing with that so they always give it the chemical bomb test whenever I go through the security gates.
The other nice thing with these cases is that it's easy to use virtually any standard graphics card as well.
 Looked again and they have my model on their site still.
