Mounting 2 SSDs with dubious 3D prints in an 5.25" bay is much less terrifying, then a 3.5" hard drive there. They are so light, the power cords might hold it roughly in place, if it all breaks apart.

Of course, all this only necessary because I cut out the 3.5" bay to fit the new GPU a few years ago. Might almost be time to get a new PC case after 15 year…
