I had one of these…

The matching case was like 48 pounds straight out of the box. Then you had to put a computer in it. Just the front door on the case was like 10 pounds of aluminum. That strap made that beast way more manageable. I still have that case in the basement. It was just too ridiculously solid to get rid of.

Now I have a gaming computer I can shove in a backpack. Computers have come a long way.
