Exactly! Even if those lower-row Macs aren't crushed into oblivion some day, I guarantee there are holes in those grills on top!the vent grilles on top were never designed to support the force exerted by the focused weight of the mac vis-a-vis its feet.
With that said, this certainly would be FUN to see if a little creativity was implemented. Imagine if they were all plugged in and attached to power strips with one master switch. With the flip of one switch, they all come to life and boot off floppies in the internal drive. Specially written software on each disk starts an animation sequence that plays on each of the Mac's screens, creating one enormous, animated mosaic!
Yes, I know it would be hard to keep all those Macs in synch when doing that. And of course, keeping those floppy drives maintained would be next to impossible. But it's fun to imagine.
