I'm using a sandwich style case with the PCIE port at the top of the case and the 3 scews for the slots are at the bottom. It basically pushing the card up and backwards into the PCIE extension cable's slot. No ass sag, but I can tell there's a limit to how much it would be able to handle like that. I've got a 7900xt (not xtx) so it works for what I need right now.
