Have you ever looked in the Good Wood stores? They had a sale going on a few wks ago and everything is real wood, not pressed. So it can take the weight w/o the wood bowing. It may be worth a few extra dollars and if no sale, ask them to call you when they have one. Also, evaluate what you will be storing. If it is for machines, die cutters, etc, you may need a cupboard. When you get done, share some pics for us. Have fun.
