Your mixing organ procurement after cardiac death with brain death. It's the cardiac death donations where they have to move very fast to reduce the warm ischemia time.

For brain death they can be systematic, corneas sure, but for major organs usually kidneys first, bowel, liver, pancreas if usable (usually with bickering about which team gets more vena cava and aorta). Heart and lungs are functioning throughout the abdominal portion to keep them well perfused, then each is flushed and chilled as it's passed off. So there is a period of time of ongoing surgery for this to occur.

But you're right, the process to declare brain death is lengthy and very formalized. Then while someone from anesthesia is in the room to maintain the body, they are not giving anesthesia. And definitely right about the last point, but it's a big fuck up.

I'll second that. I have a 5800x and 3070 Ti in mine, runs great. CPU is cooled with an Arctic LF 2 280 AIO, which I wouldn't recommend to a stranger as it's pretty tight and probably not great for the tubes, but the point being that you can fit some fairly beefy gear. Don't think I would would gain much performance with a larger case as with all the ventilation everything is drawing fresh air.
