(Note that the Hybrid cards in 4-way SLI are NOT GTX 1080's, But 980ti QRG Hybrids that were Shown in an EVGA DG-87 Case @Computex 2016 as a Centerpiece of EVGA's Show).

These are really nice and have been in the works for some time. While, it is not a full custom, and it won't keep up with your chiller, I think this is the best closed loop solution out there, once it's out that is. We are wanting to be fully modular, down to extra lengths of tubing incase there are connection issues, separate radiators, etc, all prefilled, and all having quick releases on them. This will also make maintenance much easier, 2 QD's and unscrew your radiator, and blow it out outside, or you upgrade to a larger case, buy a come extra lengths of tubing, bypass a card in SLI when it needs to come out for an RMA. To me that is a huge perk, shut down, bypass the card, remove it and power back up, you just removed a waterblock card and are back into windows in likely below 5 minutes.
The same radiators and parts will be used that are currently available, rads will be in several sizes but form the same line, and they are built to have that nice balance of cool and quiet.
