Standing desk - part 2

So what to do with your old desk when you made yourself a new standing desk?  Throw it away?

Nope,
just put a board underneath it,
add some wheels,
throw some file cabinets on the board,
put your tools on the cabinets

and TADA!!!!!!

a small work bench that you roll out whenever you need some extra space and you don't want to clutter up your standing desk :-D
