The ENGTS450 DirectCU Silent's 15 centimetre PCB is one of the shortest we've seen in recent times. However, the heatsink extends past the PCB, bringing the overall length of the card to 19 centimetres (the specifications listed on ASUS' website appear to incorrectly quote PCB length only).

Also, the two heatpipes extend quite tall and whole card takes up two slots, rendering it incompatible with most ITX setups.
