Those are for watercooling pipes.
They are for custom water cooling loops.
The radiator would be external.
You could custom mount a radiator to the bench by all means, but the bench itself does not support one.
What about this image ?
Looks like a viable option to me. Dunno if the screw holes would match up to the pre-drilled ones on the bench, you might have to tap your own.
Also, might have some stability issues lol.
