I would never again buy a 12 inch tall front opening enclosure. If it has sliding doors and a lip top and bottom the opening can be quite small. Mine the opening is only 8" it is hard to get in and clean. I love 16" tall enclosures I have a number of them 18 is ok it is a bit too tall making heat and humidity a bit more difficult, although not impossible. I would avoid a top venting enclosure as this compounds the issue.
I would also avoid wood, wood composite cages. They have a shorter life span as they often start to come apart after a while. They limit heating options as well. PVC, PVCx, roto are superior and have a longer useful life.
