Ditto on the ferm chamber first. Old fridges make great kegerators and they can be had for less than $100 if you keep an eye on CL. They don't need temperature controllers to keep kegs at serving temp, you can mount shanks/faucets right through the door with no worries of hitting coolant lines and they are designed to run at "fridge" temps without any of the condensation issues that plague 40*F chest freezers.
