i have lots of boxes like these filled with various hobby stuff. I keep two boxes on my desk though, one labeled 'A' and one labeled 'B'. Any time I use something like a tool or microprocessor or cable it goes in the A box, when the A box gets too full i pour some of it into the B box. When the B box gets too full i put the contents away where they belong. It's basically like a 2 stage MRU cache of my hobbies, all the stuff i'm currently messing with is right there in the A box or, if it's been a while, in the B box. If i'm doing something new i have to get up and go get what i need from the shelf or other boxes.
