well, but take a picture for the PCI-e connector of a Neptune cube must be a rule..
Shipping costs seem quite high for me (to Italy), but i'm concerned only on knc 2Cube+Controller+serial ribbon cable, without PCI-e cable.
I think shipping inside EU is not that expensive for just the Cubes and the Controller around 50 Euros with GLS.
