Your build was freaking awesome!! I've been following it. Tank holding strong?
My tank is great. 19mm glass was used. The big sheets took three of us to move...they are heavy.
Actually, my whole tank has met my expectations. I would just copy it.
Don't go less than 30". I'm happy with my height but looking at the 240g next to it, I know 24" would be too short. 36" is even better, but then it got ridiculously expensive. Good Luck!
