My 400gallon is 30 inch tall and 6 feet long and my glass is 20mm thick. At that thickness I don't notice any bowing. 1/2 inch might be too thin for 28 inch (70cm) height. I think 3 x 2 inch drains is perfect and you have leeway to adjust the turnover if you want. Just my opinion. Sounds like it's going to be an awesome tank.
