quick answer, yes that's plenty big enough. I keep my large adults in the 41 qt sterelite storage containers and my smaller adults in 32 quart's. They all have plenty of room. The main thing you have to consider is being able to create the heat gradiant (hot side/cool side). Some people keep their animals without a hot/cool side with no adverse effects but temps must maintain in the mid to high 80's. Good luck with the cage and post pics when you get finished with it.
