Has anyone managed to run the Mac Pro cylinder with the case off?

There seems to be an "invisible" sensor somewhere.

Thanks,
Alejandro

Saw a video posted here a while back. There is a magnet inside the case that trips a reed switch sensor on the Mac. I can't recall, but it's on the back, near the connections. Should be easy to find by taking the case off, and probing around the inside with a small metal object to locate the magnet.

Why do you want to do this?

The case helps direct the airflow, and if anything comes into thermal contact with it, it can also be used as a heat sink in it's own right. Without it, you'll run a real risk of insufficient cooling, causing component failure.

I want to test if the GPU runs cooler or hotter with the case off. That's what people do when they own stuff, they play with it :)

I noticed a little magnet on the lock switch on the inside side of the case, so maybe I need to find a little magnet and position it where the switch is to activate the reed switch sensor.

Thanks,
Alejandro
