If you would like a specific style of bracing, overflows, and/or holes I would have the whole tank custom made. If you feel confident you can even drill the holes by yourself.
For what it's worth, both of my tanks were custom made.
Thanks Viper, there wont be any holes or things that need to be drilled, but im definately gonna have alot of things hanging on the back, lol so I can stick with a ALL GLASS AQUARIUMS 75 I think. Its funny that 4" less in hight holds 15g of water, wow
