HERE me again, with the PART 2!!
This is almost the actual configuration, where all the parts are written in the #1 post.
So, looking at a few builds here in the forum, I've seen users putting 2 GPUs inside sff cases.
I've started to wondering if I could have the same in this sub 10L case as well!
And more I was looking at it and at the space, more I was getting positive about the idea!
I knew from around the forums, that in general for a watercooled loop, to have a good amount of cooling power, you have to consider 120mm of slim rad for each component, so I had to exclude my second GPU, a Titan RTX, to be under water. (SPOILER: I will do it ANYWAY, I want to check this option just for a test and my knowledge! 
)
BUT, to have to GPUs with an ITX MB, you have to use a bifurcation riser that split the x16 lane to x8/x8, and a motherboard that support it.
The ASUS doesn't allow it, so I had to switch motherboard, and after a few check, I've decide to go with the Gigabyte Aorus Pro X570 ITX. It has a few VRM phases less, 1 fan header less than the ASUS, but still 2 M.2 SSD place, and a kind of stealth look.
And the most important thing, IT offers the bifurcation support in the BIOS, not only x8/x8, but also x8/x4/x4 and x4/x4/x4/x4. SO GOOD!!
Found the motherboard, now it's time to look for the bifurcation riser!
There are a few options around, but I already knew where to look for: C_Payne Risers
This guy is the GOD of the bifurcation risers! There are of any kind, and you can even request one just for your case.
I went for the 1 Slot space one, with the brackets to support it for the DAN/Ghost S1, thinking that based on that, I could reverse engineering the brackets to fit the special riser mount support of the T1.
And I did it!! (Well, I made a small design mistake, so it is not perfect, but it works! - BTW, working with him for a 2 slots space riser as well, that can fit the T1, stay tuned!!)
Here the amazing riser!
To connect it to the motherboard, I really recommend the ADT Link R33SL riser of 25mm. It works like a glove, and doesn't touch the slim fan below!
Time to check the space and the fit of the GPUs! I've switched the case configuration to the 3 Slots one, giving me the possibility to have one watercooled single slot card and one on Air, easy to swap BTW!
Because of the two GPUs, using 2 power connectors each, I had to make my own double crimped power cable, to minimize the amount of cable coming from the PSU.
It was a pain in the ass at the beginning, but thanks to [USER=7241]@pslate[/USER] that has suggested me to use a different terminal made for thicker cable, I was able to get them done!
Finally has arrived the time to put the build together, and rethink the tubes routing, as well, not having the space in the GPU side anymore to run them.
But this time I really wanted to try to fit also the 25mm fan! To have this done, I had to push till the front the radiator. But because of this, the pump block was not fitting anymore, going against the front structure.
Thinking how to solve this, I've found this tiny AMAZING fittings from Barrow/Bitspower, that allows you to offset of 6mm anything you want! I've used 2 of them to have different degree of rotation and positioning... AND BOTH OF THEM FITS! THE PUMP and the FAN!
(Because this motherboard has only 2 Fan header available, I have to connect the 2 different fans with Y splitter. It's not ideal because of the different speed, but it works! Maybe I will use in the future an AquaComputer Quadro to control them separately - it fits, I've checked )
NOW THE BUILD IS COMPLETE!
There is also space for a small NOCTUA PMW controller to fix and cap the max speed of the fans!
Time to fill the system again! And thanks to a lot of small and important decisions, this can be done with everything in place, because everything is accessible! (Of course I did a leak test before )
AND HERE YOU ARE!!
I cannot be more happy!! (OR MAYBE I COULD?? - a small PART 3 in the next days!)
Cheers!!
