I recently got 2 Alienware R12s for a really cheap price (like bellow motherboard price), only catch, no gpus, the peels are still on, he showed me the system working,  but i had a question, i only have a spare gtx 660 atm (trying to get my other machine from office which has a 3060 to home), will the gtx 660 work on my machine? I read about safe boot and bios settings, but if i have to do bios settings i might have to get a dell gpu.
