Upgrading to a new 120 gl Rimless

[Sums24]

Well I'm refinishing all my floors in my house so since I have to breakdown the tank to do that, I figured I would upgrade. I'm buying my tank from glass cages. I know that some of the reviews are not the best but my budget is not very high. With that said I have attached a link to a sketchup model of the stand I will be building. I was hoping some of you guys could check it out and let me know if it is structurally sound. I'm pretty sure I over engineered lt but I would like second opinions. My second problem is I will be temporarily putting all corals and livestock in a rubbermaid container during the whole process. Im not sure the rubbermaid is the best option but again the budget is a problem. Any advice would be much appreciated.
