SilverStone PT13 + ASRock Q1900TM-ITX

SilverStone PT13 is possibly the smallest PC case on the market. Offering just 1.4 liter the diminutive chassis can still accommodate a fanless motherboard (here the Q1900TM-ITX) thanks to its numerous air vents.

Special thanks to our friend Tony Ou from SilverStone for sending the pic. Now we need a taller version for more passive cooling options ;-)
