I was planning on replacing the entire coolant tank as I'm not sure exactly where the leak is. I was able to get a camera under the unit and did see some buidup on the bottom. This is where I am assuming the leak is.

Good stuff. Sounds like you are on track to keep it.
For the coolant tank, as with most parts 'Porsche brand' is the best one to get. The Only alternative that I'd trust is this one: Coolant Expansion Tank 99610614708Y - OE Supplier - 996-106-147-08-Y | Pelican Parts
There are a couple good DIYs that I referenced recently when I did the one in my beater/project car:

Also possible the coolant cap or the O-ring on the pressure valve could be the leak. If the tank is original and suspect, might as well replace it though.
