looks like the back has spots for a single 120mm CPU AIO radiator and three 120mm for GPU AIO radiators.
To increase utility as a product, I would remove the 2 yellow spacers on the back between the fan ports and have that be one big fan port so that liquid cooling radiator mounting options are more reasonable.
Here's a quick sketch
Were I scribbled is also a bit of wasted space that could be utilized for a rad mount.
And another suggestion, since this is a PC case not a fridge / PC case combo....
The front vent is not enough air, you can run a simulation in flow design to see what I mean
Would suggest adding 6 more air intake vents with that black mesh filter in the crevices of the front of the case.
That would allow for enough airflow to cool an expensive performance gaming PC... provided the back is fixed so that a 360 AIO rad could be mounted on the back right. And you could easily fit another 240 AIO rad by removing that one part I scribbled around for a rad mount.
Just my 2 cents.
I'd be wanting to buy one if those issues were addressed as it would then work well for a new performance build when the Ti Volta is released
