@ IMtech: Yep, the 10-pin one at the back of the SAS-cage.
Had a good look at Molex's site, but, comparing the keying, couldn't find any tha would fit, hence me getting the pcb connector with mating plug.
Look the same, exactly the same footprint, just means a bit of soldering. If you can find me the right part though, I would be appreciative. I would probably take 5, just for future use too
