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.
Not to compare, but I remember I had put a few olden (20 years old at least) lego bricks from my childhood together and made a support castle underneath an XFX brand 6700 XT with 3 fans.
I'll get it shared tomorrow. It's designed after a bottle jack but is completely threaded to allow for adjustment and doesn't have any of the handle components, obviously.
Fuck that thing. THREE slots? I had to abandon one project and look for alternatives because my GFX card already block one slot from being used, but blocking two is crazy.
I purchased both the 7900xtx and a 4090. Kept the 7900xtx. Absolutely adore this card. Being a Linux nerd made it a no brainer, but the performance vs price ratio wasn’t there.
