I'm in the same boat..... I have a box the size of your new one I have outgrown. I have a bad habbit of buying my own tool instead of borrowing. Even if I only use it once. I also have a Smaller box for my electronics tools, o-scope, bench dmm, ESR meter, powerr supply etc. As my wife says I have too much useful junk. Lol!
Good buy on the box! Enjoy it.
