Yeah, thanks for the clarification. I know I infodumped a bit, but when it comes to safety I tend to like to make sure to mention the worst case scenarios.

If you will have additional support and a shelf below it, it might be ok to use, but yeah without a drill to make some new holes in some ears meant for another device it’s hard to say if they’d be compatible. Hole patters like that which attach on the device as opposed to the rack or standard components can really be any pattern. They have to account for both the structural integrity of the case of the device as well as what is underneath and thus would be exposed by the holes.
