First of all this tank is in preliminary planning phases and probably a couple years out still. Wife gave me the go ahead to starting accumulating supplies and design aspects. I have heard- yet never seen- of people designing their tanks to have one of the panels machined with a “u-shaped” channel to act as a weir to an external overflow box. This is extremely intriguing for me for aesthetics and wonder if anyone has ever done or seen this?!
Let me try to explain better:
-A tank wall (mine will be a side panel) is machine cut almost coast-to-coast to the water level
-This cut then acts as the lip to an external overflow box plumbed in the Herbie or Bean Animal style of drain
- There is NO INTERNAL BOX at all! Just a channel/groove cut on one wall that allows the water to skim over and out of the tank
Anyone have a photo/video of this setup and running?! I’ve tried to search for pictures or posts on many forums. I found this mention from @MaccaPopEye:

I don't know if they do them elsewhere but in Aus I have seen a few tanks (glass and acrylic) where the plumbing is in an external box and there is no internal box. The water flows over a groove in the back panel and into the external overflow, this groove is machined in (like a very wide U) and replaces the internal box and drilled holes. So in that case there are fully external overflows, fully internal overflows, dual internal/external overflows (like the ghost) and hang on the back/siphon overflows.
