** Just a quicky, about leaving the covers off. Though it helps
**with thermal problems, it may create other problems. I know someone who
**built a 3000 out of spare parts. He had no chasis or cover, and had
**bookoo prob's with all the radio intereference.
Another problem exists with leaving the cover off. The fan works on the
principal that it draws air THROUGH the chassis. On the 4000 for
instance, the "vent in" holes are on the right rear (when facing the back
of the machine) where the video slot/PC slots are. The fan draws air
through to the left rear. The Toaster card runs very hot. If you also
have other cards installed (e.g. TBCs or Audio cards), the heat just
"stacks" up just like the cards. Without air circulating through the
machine, you could damage one/all of these boards.
Leaving the cover off the machine won't help much. The fan won't do a
thing since it PULLS air through the machine. With the cover off, you'd
just be pulling air from the areas immediately surrounding the fan.
Might not even cool off the '040 nearby or the HDs.
