Cabinets: the 3 door harbor freight metal cabinets ($35-65 ea, depending on sale/coupons) are exactly the right depth for 1 gallon cans; whether square or round. I have 2 walls worth where I organize & store all my chemicals and consumables.... Thanks -S Scott Cypher SCCA #562573 HP Spitfire 1500 #57 Http://gallery.mac.com/srcypher
