The owner's manual does more than not recommend this, is says quite
positively "don't do it." There is a right/wrong picture with a big
red "X" over the vertical Mac II.

What's not clear is the exact reason for this and whether a stand
changes anything. The text says 

	Proper ventilation is important to the life of your computer
	Be sure to leave a 4- to 6-inch clearance between the side
	vents on the main unit and any object that might restrict
	air flow. Always keep your computer's main unit flat, sitting
	on its rubber feet. Standing it on edge defeats the cooling
	design, and is likely to make your computer overheat. This
	will eventually damage the main unit.

Is the problem only that standing it on edge right on the floor blocks
the vents, and therefore is OK if you put it on Kensington's stand, or
does vertical orientation not support some assumed convection in the
cooling design?

Also, what about dust? If you put it close to the floor will that be a
problem? The manual mentions that the vents on the sides are exhausts,
with the intake on top, which would limit this problem. (It also
argues against any needed convection in the normal orientation.)

In the latest Businessland catalog, the Kensington stand is described
as "the only Vertical Stand that's recommended for the Mac II." Is
this just hype or has Apple Ok'd it in some way?



Anybody had any lengthy experience with vertical Mac II's?
