This is nice, but I just built my first ITX based SFFPC in the GEEK G1 SE and would consider it to have fewer frills, while not requiring assembly, and about half the price. I don't see it mentioned too often so wanted to share it as an option if you want to go this route but keep it simple. Great airflow too :)
