Clearly he is going to want the black since it seems like it would offer more cooling. 
 
It's a great looking build with some serious power. A system like that probably could run Crysis.
 
 

These guys are typically slow in getting orders out, but I do like their gear.
 

Nice looking order

So, great job Watercool.de

Does help being 'next door' to them. 

So ... it works!
Had to remove the 4 pan head screws from each card to install them without putting too much pressure on the pcie slots. (the entire cooler will go from each card anyway when I fit the waterblocks). Was concerned about suffocating the fans but they ticked over nicely at 35-37C.
Main aim for this was to setup and test the ADD2PSU adapter, linking the two AX1600i psus.
Will try a folding run tonight, just on air, but will have to power down at least one of the other rigs as I'm not sure what each psu will draw at the wall at this stage. Having to spread the load around the the apartment.
Anyway, just thought I'd post a quick update ...

 
 
 
 

very nice, hope the testing on air before custom loop goes well
 

So are those cards all linked and running sli with the Nvidia driver mod and without an nvlink adapter?

Love the RTX line, one thing that surprised me however is that they no longer offer peer-to-peer through pcie - unlike several generations of previous GeForce cards which DO offer a pcie p2p bus link. see: Unified Memory Architecture.

That’s a bit of a big deal for compute-centric uses. Even if you didn’t have the speed of an infiniband or NVLink - on previous gen cards you still have the ability to use a single merged memory space for a large DL model at slightly slower speeds. Hence, on Linux (not Windows) every previous gen GTX card could access each others page space in pcie - without going through the cpu memcopy - which is very unstable along with slow.

The RTX cards offer, at most, 2 cards in UMA through NVLink... but no option whatsoever for pcie memory sharing for additional cards. So other cards, outside of the 2 connected by NVLink, are cut off from a single merged UMA altogether.

pcie used to be a rather nice fall-back when NVLink wasn’t there for above stated reasons.

NVLink >> pcie >>>>>> memcopy through cpu

I believe they are independent cards --> for a Folding @ home project -- SLI does not help
