That's the idea. I'm toying with the idea of mounting the two PCs I use under a shelf, hanging rather than sitting on a surface. I still want enough room on the shelf to put other components (router, gamepads not in use, etc).
It might end up being a lot of extra use for something there is already a solution for, but I really want to build something almost for the sake of building it, to tell the truth, and I like the idea I have in my head, so I'm just gonna go for it.
Thanks for the tips. I think the flexible solution is the way to go. Makes what I want to do that much more feasible!
