I have the board in an Antec case with PicoPSU and SSD installed as HTPC and can only say: PERFECT! The PC is really absolutely silent (also due to the passively cooled CPU and graphics card), decoded HD material in MediaPortal easily and even upscaling of SD material in it. Only the built-in 4GB of RAM can not be fully utilized. Since Asus now offers also similar boards with i3 / i5 CPU, I had taken a newer board eye for my next HTPC, but it was clear from many postings that only the AT3IONT REALLY be operated without a fan in the long run.
