Akasa Cypher Thin-ITX enclosure (AK-ITX04-BK)
The new Thin-ITX enclosures Cypher, Euler and Galileo from AKASA are designed for Digital signage but also work perfectly for other applications.
The enclosures are built in aluminium and are suitable for VESA mounting. These enclosures can take Thin-ITX mainboards fanless with CPU TDP up to 35W. With 35-65W TDP there is an additional low profile fan needed (only available for Cypher-model).
A nice looking case for the price with large enough vent for a 80cm fan so you can install a fan and keep it at low rpm so it's inaudible, just so the components get some airflow. The power led is very bright, so you might want to either not connect it to the motherboard, or unscrew the front button circuit and tape over it with electrical tape. Put some foam between the panel and power/reset buttons while at it because not only they feel flimsy and cheap but they actually rattle when you move the case.
