The site refresh has inspired me to dust off this old thread and post some updates.
It was 12 years since my brother passed away last month, so I thought it was time to re-organise the garage to fit the last of his toolboxes in.
He was a motorbike mechanic, and I've had his two smaller toolboxes at my place for years, but the big base cabinet has been at Dad's place.
That's in the middle of moving those two workbenches down towards the wall to make space. The two smaller toolboxes are on the right.
Here's the full stack...

With visions of my son using the drawers as a ladder and pulling half a ton of tools down on himself, I thought I'd better attach it to the wall.
Why buy something for 2 dollars when you can spend hours making a worse one!

No clocked screws here. Those concrete Tapcons don't like being overtightened.
A bit of 500kg paracord should keep it upright...
And the after pic...
With some floating shelves for helmets where the toolboxes used to live.
It's still a mess, but trending in the right direction.
