I know that it would be to much "awesome" in so compact design but is there a possibility that we can use that fill ports as regular intake/outtake? :)
I created simplified 3D model for AM4 socket in cad.onshape.com/documents/9e98f9518667ab2f8ad819ef - you could export file from this viewer :)
It should has good dimensions but I can't guarantee that ¯\_(ツ)_/¯
Its good to know - I have plans to use 5900x with 3070 fe but with flex-atx 500 W psu - should be ok if we assume that 3070 uses 100 W less than 3080 ;)
I know that you decided to create a new build but if you want to give a chance to this one you could try Alphacool Eisblock XPX 1U water block. It should has better temps than this one from ali :)
@kai535 I think that both stuff you mention:
are mutually exclusive ¯\_(ツ)_/¯. Simply widening the case from 66 mm to ~86 mm will increase it's volume to ~9 L :/
