Does anyone have additional info on the top fillport version of the T3?

I tried looking back through the threads and see mention of it, but I couldn't find any pics of it or whatnot. Primochill's site also doesn't have any top fillport specific pics of the T3.

Is it basically another G1/4 threaded port in the top of the T3, like around the area of the inlet ports on the back of the T3?

Just seeing if anyone has a pic or can explain what it looks like and/or if you can see that top fillport from the front.

Been thinking of getting a new T3 with the top port to maybe use one of those aqua computer Tubemeters with it... Just thinking things up
