Streacom DB4 is a passively-cooled silver mini-ITX cube
 

Fanless case specialist Streacom is releasing the passively-cooled DB4 mini-ITX chassis today. While cases with integrated passive cooling aren't a new thing, the DB4 is noteworthy not only for its distinctive design, but also for its motherboard compatibility. Streacom says virtually any mini-ITX motherboard will fit in the case, a characteristic made possible by the fact that the mobo is mounted parallel to the case's side panels. This in turn allowed Streamcom to use a sharp-angled heatpipe design that needs little clearance around the CPU socket.
