Hehe, yes PA is awesome for some stuff. I also found some gas shock thingies like used to open a hatchback car for $10 each. I was going to use them to open the top and hold the lights up, but I think they are going to be too strong. They are 265 lbs, and only 13" long. Will take quite the lever to close them and I don't think an 18" canopy will be enough.
This whole DIY thing sucks...I really don't enjoy it at all. Grr... I didn't think of using any fans going upwards...that's a good idea. I need to figure out a way to have the lights out of my way so I can get in the tank easily. This is why I was thinking of using the shocks to lift the lights out of the way.

86cfm is plenty - but don't have one pulling & one pushing... Use a passive air intake (down at the bottom of the fixture) both fans at the high point pulling hot air out; try to ensure you're not restricting the intake (lots of info on how to size an air intake can be found on google).
As for the gas charged shocks - Bet you'd find they're useable, but you might have to play with the moment arm a bit - becomes a trade off between opening enough vs opening/closing easily... Betcha bandit could make you a pretty drawing to show what I'm trying to say...

I got my fans from Memory Express, if my memory serves they are running 37cfm at 18 db. I love how quiet they are, I have 2 pushing and 2 pulling from left to right, they work great and you cannot hear them.
