dresser with false drawers. lined with pleated mylar, 250 hortilux with digital ballast, s&p 5" exhaust, built the exhaust adaptor with home depot hvac adaptors, the back door is sealed with rubber weather stripping that fit into the ledge perfect. excellent seal, have pvc elbows under to bend the light, it will be completely light and sound proof,the fan makes very slight noise way way way less than my other cab which has computer fans. it also has 100 watts worth of t5's mounted on the top. the bottom is coated with rubber undercoating so its not destroyed by the moisture. I just need to finish wrapping up a few things and it should be running by tonight. Thanks for looking
