well im not sure if you already are.

but going back to your first post, i see you have two identical rubbermaids. have you thought about stacking them for more room? it would help out considerably with the 150w in there for more breathing room. u saw somewhere on one of these sights where someone did a DIY cooltube. now im still a noob so im not sure how much space the cool tubes take up but if i can find the link i will post it up for you, i think it too will help out greatly in your rubbermaid box if it is plausible.
