This may be a dumb question, but it was one of those oddball ideas that tend to strike me at oddball moments.
Thinking about my pending kitbuild project, I realized that cooling in the typewriter case may prove problematic. Obviously, I could simply cut sufficient ventilation slots in the case's body. But then I got to thinking about fans instead.
So, the idea I had was to supply power to the amplifier via a sufficient computer power supply, and also run a small internal cooling fan off the same supply.
I've never seen, nor heard of this being done before so I wanted to run my random idea by the amp wiseguys here to see if that's even possible to do.

A computer power supply makes highly regulated and filtered DC voltages in the 5 and 12V range. It makes nothing useful for an amp. You can by a fan like the ones in computer power supplies that runs off of 110V - at Radio Shack. If you set it so that fan blows OUT remember that there must be a place for the air to come IN, and vice versa. Usually the inlet is covered by foam rubber to avoid coating the insides of your device with dust.

I gotcha Greg. A different approach I thought of that seems far simpler is placing a simple power strip without a switch in the bottom of the case, make the strip's cord the one that runs out of the cabinet to plug into the outlet, and then just plug the amp's power cord and the fan's power cord into the strip. Maybe mount an on/off switch for the fan somewhere so it doesn't immediately kick on when you plug in the amp.

So, one of these could simply be wired up to a typical power cord? Or would it be more prudent to wire it off of the amp's power cord?
