Just to clear up a bit of mis-information. On my machines (and about 90% of
the machines I know about) it is *not* the power supply that fails. It is
the flyback or associated circuit. Both are on the analog board, which many
dealers simply (and incorrectly) call the power supply.

I've got one machine that I've had since the days when a 128K was state of
the art. It's blown the flyback twice. The last time it blew was a little
over two years ago. The other machine blew the flyback a couple of months
ago, after almost two years of service. Both were used seven days a week for
(on average) four or more hours a day of service. Neither is left on when
it's not going to be used for a period of time (turn on when you get home,
turn off when you go to bed. Constant power cycling isn't good). I'll ad
that both machines have Dove memory board upgrades, which significantly
increases power usage and internal heat. Both also have fans.

You can expect that. Macs work just great without fans. However, heat causes
components to fail faster. So even if it isn't necessary, adding a fan
lowers the internal operating temperature which reduces the rate at which
things go blooey. (in my eyes, a case of pay me later or pay me much later.
I think a fan is a good investment).
