My big cab is similar, but it's a bit wider: 72"h x 47"w x 20"d. And it's wood. I'd avoid metal unless you have the tools to cut the metal to provide ventilation and a hole for power. Actually, I'd just avoid metal, even if I had the tools to work with it; just seems like it'd be a whole lot harder than working with wood. But size-wise, that's fine for a few plants.
