Summary: Be careful about Intel video drivers. Intel has definitely not matured compared to AMD in bringing stable drivers to the market. If you update the video drivers to the latest release from Intel, your system will crash (BSOD) if using HDMI - guaranteed!!! Use the drivers from ASUS website and you will be fine. If building an HTPC, I would definitely consider the new offerings from AMD - particularly there new F1 socket CPUs and motherboards.
Summary: The board goes together easy as pie and as long as you aren't planning to use the IDE hard drive port, you shouldn't have any issues with space. The only reason I knocked from 5 stars to 4 stars is that I hooked this board up to a 21" CRT to configure the system since I was going to run it as a headless HTPC and the fancy new graphical BIOS screen would not display properly on the monitor at all.
