(1) the mac ii blows air out of the left side. i just put a piece of
    paper on the side of the mac next to me and tried it.
(2) yes, if you are going to put a mac ii on it's side, by all means
    raise it above the floor for ventilation.
(3) however, if you are going to put the mac on the floor, put
    the RIGHT side down (near the floor!)
(4) the power supply will be above the board and hot air (which rises, of
    course) will be pulled up by the fan and out of the machine.
(5) yes, the interrupt and reset buttons and the disk drive are a pain
    to have to reach when the mac is in this position.
(6) the 40 meg hard disk in this mac is made by quantum, not seagate.
    this mac has been on it's side for many months, and there hasn't
    been a single problem.

    does anyone have comments or corrections? does anyone else use a 
    mac on it's side?
