I couldn't find this info anywhere online so I post it here where I think it belongs and will be more useful.
Shuttle PC62 cable lenghts (click picture to view full size):
A = 85 mm = 3.34 inches (to the tip of the 4-pin connector)
B = 280 mm = 11.02 inches (to the first black molex connector)
C = 195 mm = 7.68 inches (to the first black SATA connector)
D = 170 mm = 6.69 inches (to the tip of the 20-pin ATX connector)
E = 530 mm = 20.87 inches (to the first black molex connector)
* All measurements from the psu metal casing
I hope it helps.
