Pure reef also carries them. I think the deep blue has that dimension as a 60g also. I went with the 80s for a little more vertical room for the Vortechs and also account that higher water level is tougher to maintain on a rimless tank.
I'm pretty sure deep blue has the exact thing unless you want something a little nicer. They're very affordable tanks but not top level craftsmanship. Great frag tanks IMO for the money
