Can anyone recommend a good ATX case to house an EVGA hybrid 30XX GPU (with 240mm radiator) plus an all-in-one CPU cooler (with 240 or 280mm radiator)? I was considering the Lian-Li O11 Dynamic Mini, but it seems odd to position a radiator at the top of the case taking in air from above. And, there doesn't seem to be enough clearance (for an ATX motherboard) to position it at the bottom of the case.
 
When EVGA moved to 240mm radiators for the 30XX-series hybrid GPUs (I have a 1080 Ti hybrid with a 120mm radiator), how did they imagine these radiators would co-exist with AIO CPU coolers with their own 240/280mm radiators?

corsair 680X works, thats a 280 on top 

My 3090 ftw3 Hybrid is in a Thermaltake View71 (it's a nice case), the best place for it is up top with a push/pull setup blowing the hot air out, I've got 2x140 at the front and 2x140mm at the bottom pulling fresh air in and 1x140 as exhaust, there is still room for your other radiator at the side.
The downside to the small 240 Hybrid radiator is if you have a large monitor and like to play at 180+ fps. I had to limit my fps to 120 on my G9 monitor for the heat in the room was unbearable from such a small radiator, with fps capped at 120 my Hybrid is in the 40's and maxes out at 55ish, if I go to 240hz and cap it at 230 then you can add 15 onto those temps (but the heat!).
 
After buying the 3090 ftw ultra Gaming air model and then upgrading it with the Hybrid Kit I finally realise that these things need to be in a water cooled loop, so I've purchased a Corsair 1000d and my Optimus ftw3 block arrives on Monday, other parts to this new build arrive daily with the exception of my fans which have still not arrived at the shop I purchased them from. If you plan to play on a large high hz monitor then make a water cool loop with decent sized radiators. 

Currently running 011D-XL with the GPU AIO as the exhaust on the side.  I have the CPU AIO on the top as ingress along with fans pulling more fresh air on the bottom.  I also have a 120mm on the back pulling some of the extra heat of the CPU out of the case before it can saturate much of the system.  I have a fairly high room ambient temp of 80 F ~ 26 C and my system CPU and GPU idle around 29 C.  Under load, my GPU will just barely break into the 60s and my CPU will be similar.  Though the cooler for the CPU admittedly needs to be replaced but then again so does the CPU.  I am in the middle of an upgrade atm struggling with waiting to see what is going to happen with intel.  You can check my mods rigs it has the specs and link to pcpartpicker for more detailed parts breakdowns.  With this setup, I currently have the highest timespy score in the world for my hardware.
 
edit: I'll also mention my buddy runs his in a similar configuration with the 011D-mini and it works pretty well. I don't know the exacts though on it.
