Does anyone know where I might be able to find this product in NZ? http://www.dabs.com/products/startech-com-6--sata-power-y-splitter-cable-6LC9.html

I already have one of these: http://pbtech.co.nz/index.php?z=p&p=ITPAK-SATA4&name=Dynamix-Dual-Port-Serial-ATA-Power-Cable-Splits-1x

But I fear the male end might be too large for the space (the inside of an iMac), with the superfluous (in this case) 'white bit' (IDE?) being attached.

Any help would be hugely appreciated - am wanting to source it locally as it's for an urgent-ish project.
