Just use the search functionality and search for "keezer". I don't expect many people to be posting a list of parts and steps as this is a pretty major project. You'll find many different threads that use different parts and different methods of construction, so there really isn't a list of parts set in stone.
ok i didnt know it was called a keezer lol that may be why i didnt find anything but what i want to know what are the major componets or how does it work like with the c02 and all
so am i right or wrong about this all i need to make a draft system is a pressure line into the keg from a co2 bottle with regulators and tap/ despensing line? basicly
Theoretically, yes, but only if you want to use picnic taps and open the freezer every time to pour a beer. If you want to have taps on the outside you will either need to put a wooden collar on the freezer or drill holes in the top for a tower.
Cleaning the draft lines you use BLC (Beer Line Cleaner) or some similar product. You can use a hand held device or just put dilute the BLC to its proper concentration in a corny keg, pressurize and run the solution through the lines. Here is a link to a very informative website and the photos of my keezer collar.
The compressor is in the back, underneath the hump and the coils are in the sides. Putting a tower on the top shouldn't be too much of a problem. Here is a thread that should give you a general idea on how to attach a tower to the top. My only concern is that you need the small piece of plywood to secure the tower into the lid.
