I totally agree about the need for minimal noise. Actually with the combo of contact-less U360, fanless CPU mobo and SSD I aimed for a ZERO noise-print cabinet.
Do not forget though that cooling of some sort is something you can not escape (even low power components generate heat). Neverthelesss I kept persisting on accomplishing the zero noise goal by incorporating the 120mm inlet fan which came with the PSU. The fan is virtually silent (I honestly put it next to my ear and could not hear a thing when operating). However, believe it or not, I eventually failed by not compensating for the fact that moving air by itself creates noise when forced to pass through narrow openings... So I can now clearly hear some low pitch humming from the opening at the top-rear panel as the exhaust air is forced throught the perforated metal plate that I used there... If all the components are running outside the cabinet I have zero noise, but put them inside the cabinet and the airflow around the components, PSU heat sink, cpu heat sink and perforated plate adds up! In any case the noise is minimal, quite low pitched and does not interfere with the experiense but rather adds a distinct breathing sound which gives more "personality" to the cab :-)
