I also realized that there were A LOT of pieces. The box claims "little assembly required" which I now know is a lie. I started putting it together, and after about an hour and a half later. I was finished.
Then I realized that I forgot the two back pieces, so I had to take a side off, slide them in, and re-screw them in.
FINALLY I was finished.
I'm pretty happy with the final project. I only wonder why the middle section is bigger than the other four compartments, but it is what it is (can you tell?). I followed the screw guides, so I don't think it's user error.
Either way, I'm now ready to load up on some magazines and get myself organized.
