I decided to jump in to this hobby full on and build a keezer. I also liked the idea of not having to take all the time to bottle and wait the extra 2 weeks. First I want to say that I do not consider my self to be very handy when it comes to this kinda thing so I didn't want to make any big cuts into the freezer its self. I found the Frigidaire model FFFC05M3LW on sale at Best Buy for $143 and figured it was the best time to get started.
This freezer was extremly easy to convert, I basicilly popped the plastic cover off the door hing, unscrewed the hinges and the door came right off. Then I dicided on a 2x4 because the freezer can easily fit two kegs and I don't think a 2x6 would make any difference in the effort to get a third keg in there. I had lowes cut the 2x4 came home screwed it all together and stained it. After the stain dried I attached the top to the collar using only the top hing screws because the bottom two over hung the collar on to the freezer and they didn't alight with the original screw holes. Then I lined the collar with some rubber matting I found at lowes to insulate the wood.
The only thing I didn't do is secure the collar to the freezer its self. I haven't figured out the best way to attach and insulte this part of the build. What I'm looking for is something that will keep the collar secure and can eaisily be removed if I wanted to convert it all back to the original freezer.
I got most of my parts from Keg Connection I used:
1 Keg Kit with a 5lb Co2 tank
525PC Perlic Faucet
5 1/8" shank
