Magnets instead of Pegboard

I used to work as a network administrator in the early 2000's. Under my care were a bunch of desktop computers that we used as servers. Hard drives weren't very reliable back then and the result was that I ended up with a pile of dead hard drives. I took them apart and inside I found not only the pretty disks, but also some really powerful magnets. So much more powerful than the dark gray magnets we used to have. I found a good use for them. I screwed a piece of one by whatever to the wall over my workbench and screwed all these magnets to it. They hold up most of my hand tools. I didn't have quite enough magnets and I found some more on Ebay.
