Case 1

In the first set of pictures, I was just trying to create a generic box to hold my computer together to see if I could do it.

I realized quite quickly that even though I thought I had a "lot" of LEGO blocks, the number of blocks I needed outnumbered the blocks that I had on hand. The pattern at the bottom shows the number of LEGOs I had. All the blocks above that line I had to purchase after the project was underway.
