I use this to suspend my computer under my desk using with 25x2mm straps. It's designed to protect the dust filter of a Fractal Design Define 7, while also allowing it to be removed and cleaned. This only includes the strap distance part, though. The way I attach it to my desk is part of the desk frame itself.

Computer illiterates also call this type of mount a “CPU holder”, but since the illiterates won this fight I'll include this here for people to find the model.
