In this how-to video I explain, in detail, the necessary steps in converting a chest freezer into a keezer (or kegerator). This is perfect fore serving your all grain home brew.
Aside from the freezer you will need building materials for the "collar" (2×4, chalk, screws). You will also need a temperature regulator and of course a keg full of beer and a co2 tank (with beer and gas lines).
Please let me know if you have any questions.
