the GB BIOS back door hole has been patched, so you just need to check if your mobo’s BIOS is running the latest revision.
the GPU problem is more nuanced…it is and isn’t the fault of GB. it isn’t because the end user should have known to put a GPU brace / bracket due to how heavy the cards are getting. it is as GB, like all the other AiB, know these cards are too heavy to hold up on their own and should have a brace / bracket included in the box, not as an accessory that needs to be purchased separately.
when we build a custom rig with a dGPU, a GPU brace / bracket is mandatory, no exceptions.
