A working fridge is not the ideal solution for cigar storage. Usually you cant get the temp's above 60degrees without an external controller.

A cheaper alternative is a cooler/ice chest, a search on coolerdor will give you some ideas on how others have set these up. Clean the inside with baking soda on a new sponge and let it air dry for a day or so.

Spanish cedar is available from wood specialty stores like Rockler or Woodcraft.
