@Nouvolo Aquanaut will most likely launch before this project.
I think this type of block really could use a Reservoir built in to make it easier for people. That's the game changer on the Barrow block. The trick is that both POM and Acrylic is too weak to allow the thin walls necessary for the 48mm height limit. I'm thinking maybe just making the whole thing out stainless or copper to integrate reservoir.
@Wahaha360, I have tons of radiators I can test if you need.
