Thank you all, very helpful...
Mogie, looked at the link, looking for somthing around 7 feet tall. Cute little setup though, I have figured out what I am going to do, and as of right now only have spent $25 on pressure treated 2x2's. Just going to make the walls out of Black and White Poly. I will post a picture of the setup I am going to build.
Salamandastron, Very good idea with the drywall and metal. My next one will deffinatly be made with metal studs!
Pandabear, Looked at that and wasn't sure about it (price, size, and temp.) Now that I am thinking about it, I just installed my Air cooled hood, and it would have been fine for the temps part, but I bought the 2x2s before I rethought it! lol Thanks man.
NonGreenThumb, Thats what I am trying to do. Replicate a system. But I think I am going with a 2x2 frame setup and B&W poly.
