10G on RN516?

Thanks for the idea, ahpsi. I think that's close to the right answer, but it seems that the mobo's power connector is in the way of inserting a card like the one you suggested (I bought it and tried :)

Perhaps one with a flexible cable might work? Something like, http://www.amazon.com/gp/product/B004H6044U
I'm not sure how to secure the card with something like that, though.

The location of the slot seems to be a bit different for the 716, or Netgear uses a riser card with some sort of offset. http://www.smallnetbuilder.com/nas/nas-reviews/32418-netgear-readynas-716-reviewed

ANY movement on this issue? What do you folks think about using a Thunderbolt adapter instead? There is IP over Thunderbolt...and that could be a WAY cheaper option and provide DAS to at least ONE computer!

You can't use the NAS as DAS.

I would love to find a source for that offset right angle adapter. Any one know of a part number ?

I believe this is the one I purchased:

The solution isn't elegant, but it works, and Netgear isn't standing up to its promises (again). I'm not near my nas, but I believe I installed the card and used a short cable to attach the 10gb card which isn't securely mounted. Something like that.

My only consolation in implementing such a less than ideal solution is that with the 516 being my 4th readynas this made me very comfortable with it being my last. I have a duo, an nv+, an ultra 6+, and now the 516 and I've had disappointments with each and every one (to be fair my biggest complaint with the 6+ is that very shortly after dropping the cash on it the newer models were announced and that model was left behind). After this disappointment I built a linux host with 6 drives plus ssd boot drive, hardware raid, xfs, 10g, linux, and it screams with regard to io and apps like plex. But I digress, 10g on the 516 does work, but i probably voided my warranty.
