shoggy can you list the entire wetted parts.

So its copper and steel? But you said the SLI version will have a acrylic top instead?
Is there a way you could make the top a little thicker and make the water path larger so its less restrictive?

Also any chance you guys can glass bead the interior like DD's so you increase surface area and give this block a chance with the big boys?

I want to give your company a shot at my HTPC. I have your Cuplex DI and these guys would go very nice with it.
