Replacing a thermostat casing in a 2006

Hey a few weeks ago I asked about my fan running after I turned it off. Yup it was my coolant. I have been having to top off my coolant everyday before I drive and I finally found the source of the problem. There is a leak below my thermostat housing.

Has anyone ever replaced one of these before? I'm debating taking it into a shop or just doing it myself. I consider myself handy but I don't have a lot of experience with cars. But from what I can tell it seems like you don't have to remove too much to get to it.
