Forgot this:
If your case had been installed in the machine by the manufacturer *without* the top I seriously doubt you'd have it now. (How in the world would it have found its way to a reunion with the rest of the case when the PC was stripped out? And also, why would they bother notching the corner if it was never intended to be there anyway? You can see the notch there in this photo; I'm curious what those two cables coming out the notch do, of course, but that's clearly why the notch is there.) That picture of one showing the case without the top is probably a machine in the process of being stripped down. It's missing *all* the skins off the left corner and the case bezel, which should also be there on a complete unit.
As to those "extra" clips, my case had them too. They came in the accessory bag with all the screws, they're merely not installed on the one that's pictured on Newegg. They are indeed probably there to ensure the top gets grounded to the bottom for RFI reasons.
Actually... this comment here? It's actually really a perfect encapsulation of... why this flight of fancy gets a little frustrating. You're extrapolating *way* too far for each little thing you noticed on this hunk of metal, fitting it together in your mind with some pre-boiled concept of what something would have been used for if it had been a prototype (IE, that notch in the case being a "finger hole") or how you would build something if it were you doing it, etc. It's really not clear from this statement if you think that the manufacturer of the machine added the clips to the box and ran it sans-skins so they could also use some particular bump or notch on the chassis as part of its "racking system" and that photo of the machine with the skins on it is wrong, or just saying that's how you'd do it and here's a photo validating your idea. (Despite the overwhelming evidence, a part of which is actually in your hands, that they *didn't* do it that way and that the photo that does show the case sans-skins is a photo of a partially disassembled unit?) It's just a wee bit confounding, I do apologize for sometimes being too slow to distinguish when you're just saying something off the cuff verses asserting something as an actual hypothesis.
Well, there's that other shot that clearly shows that the U-shaped case top *was* used:
