I'm gonna go against the grain and say that the idea has merit. The Asus board you mention is superior to any 1156 one due to proper USB3 and SATA6gig, and the iGPU on the 2500K is leagues ahead of the Clarkdale one. Also the power efficiency is there and the chip would transfer to a wide range of uses down the line if you decided to change things around. And the machine would be capable of a great deal more than just HTPC if you ever need it. If you have the cash, I think it's a great idea.
