It locks the expansion cards firmly while the design of the rear panel allows you to open it when the case is positioned horizontally – the blank brackets against empty slots or with peripheral ports won’t fall out.

There are no extra, unnecessary cables, wires and other stuff. And the most important thing is that I spent less than half an hour to assemble the computer – and without much effort, I should say.
