To state that laying *any* Mac II or IIx (or any Mac for that matter)
on its side is dangerous is simply not true.
Quite a number of those machines have Seagate hard 
disks, whose installation manual (Universal Installation Handbook,
Seagate Publication 36042-001, Rev D.) reads (p. 12): "The drive may be
mounted horizontally ... or on either side (egde)." I am pretty 
certain that this applies to other brands as well. In fact, in vast
majority of Seagate installations I have seen in Macs, the disk
has been installed upside down (a strick no-no, which voids your
warranty, according to Seagate). This causes "sticktion", which 
finally leads to the "sad mac" symbol and an instance of 
aggravated end-user.
