I decided the bottom will be for my cordless power tools, batteries, and chargers.
That is at least until I get tired of having them so close to the ground ( I'm still young enough that it's not an Issue for my back yet ).
I took the power strip I use for my chargers and glued a couple of neodymium magnets to it that I had laying around so I could stick it inside the back right leg of the cart, a little electrical tape to prevent scratching and it's good to go.
It plugs into the power strip on the side where I've got my 2 lights and fan plugged in, so that's basically my light switch right as I walk out into the garage.
I also decided to move the tray and handle both up so I could put the magnetic accessory tray on the left side in the spot I liked best for it, I also just kind of wanted to move the large side tray up.
The handle sticks up above the level of the top which means I couldn't use it as a work surface, but with that and many common use tools being in the top I'll be much less inclined to set things on top of it.
The lid doesn't exactly close 100% on that side now, but it can still lock, and I don't see a problem with this otherwise. There seems to be enough play in the system that this shouldn't be putting any kind of unnecessary stress on anything.
Yes I'm a bit limited in what I can put in the side tray now, but I never wanted to load it up with spray cans anyways.
