Nice! The article validated my choices - identical MB / cpu choice for the server, and my htpc has the same MB as their gaming rig, albeit without the core i5. Though I guess that may be due to the relative dearth of mITX MB's available...
Re: placement, I wanted to see my HTPC, which is why I spent more for a case I think is gorgeous.
Moving back from using laptops in the past ten years, I'm pretty much all ITX except for servers. In the interim years, desktop boards and cases made a lot of progress in formfactor, power consumption and quietness.
Built my first HTPC in a mni-ITX Antec ISK case, building my second in a Silverstone GD06. If I had the room, I'd stick it in a HAF case. One thing PC's will always have: flexibility. No soldered RAM, no cut back restrictions.
