I think after all of this the stand isn't up to par.
Might just do DIY stand. I got all my equipment just can't pull the trigger on finishing it. For me, the overhang right to left is right on the seams. Front to back is good. Now I am doing what I should have done is done DIY so I can use and have plenty of sump room for the equipment I got. You are the 5th person to tell me to avoid that stand like a plague one guy showed me in a video as his stand broke and he just couldn't sweat it any longer before the tank busted.
Good call! Now you can make the stand exactly how you want it and sturdy enough to last for years.
