I have a device like this and it supports heavy gpu inside my pc. Wery usefull and nicly built thing made from metal. But the consern is it has a magnet on botom side, so it sticks to metal surfece inside the case. Wery usefull again but my hard disk is under that metal surfice. So i wonder can it corupt data or damage hdd itself..?!
Fields from magnets can, just depends how strong and this applies to spinning hard drives not SSDs. We had an idiot at work once that decided to store a bunch of magnetic bases on the top of a tower PC. Corrupted the drive. This case there were quite a few of them maybe in a half dozen to a dozen range and they were the strong lockable ones for breadboards.
