our loaner chassis from last summer was a GPU chassis, should have told me to do this before. we swapped to hardware we were supposed to the week after we were off the loaner but it was left as-is until we had time to move it. can't use the old chassis now because they changed IPMI info and with the user privilege they had they could have installed modified bios. checked versions and they matched but you can't be certain when somebody has that kind of access to the physical hardware
