We found a peice of melamine for 75% off yesterday, so we have one enclosure pretty much ready to build. We picked out some tile and bought enough for both of the enclosures. I think we are going to use the 100watt Megaray MVB's, one in each enclosure. I am thinking that will hold temps where we need them, but if we need another bulb at the cool side, that wont be hard to do.
