Antec makes "fan quieting kits" for about $10, which consist of a rubber
square for the fan itself and screws rubber washers for the screws. Of
course, this only solves your problem if the noise is being generated by
vibration of the case by the fan. If the fan itself is noisy due to poor
bearings or just operating at a very high speed, you could replace it with a
silent fan and do the wiring yourself. It won't be as simple as plugging in
a molex but with a little electrical tape and some wire cutters it shouldn't
be difficult to figure out where the connections go.<!-- ~MESSAGE_AFTER~ -->

  You may well get by without the case fan operating, but most of the
time manufacturers do not add parts to a system unless they believe they
are needed. Alby's suggestions were good, but watch the behavior
closely and if there are adverse results, get another fan or fix the one
you disconnected.<!-- ~MESSAGE_AFTER~ -->

What it is that bugs me the most is a regular vibration that comes
and goes every few seconds, and lasts for a few seconds. I tried
cleaning the dust off the fan blades, but this didn't get rid of
it. I tried mounting the entire computer on a foam slab to soak up
the vibration, but it only helped partially. It seems to be
emanating from my case fan, which is screwed into the front of the
case near the bottom. When I press my fingers against the case
near the fan, I can feel the vibrations coming and going.

I'm not sure I can track the fan wires back to where they plug
into the motherboard. I will have a try. If I can't do it, I will
take a chance and just cut the wires, and see if the box overheats
without them. I'll also disable the fan speed monitor in my BIOS
first. I really don't think the CPU will overheat, since it has
its own fan, and the box is large, with plenty of open space. I
can always reconnect the fan if it does overhead, or buy a
replacement. The only risk I can see is that, without a fan, the
operating temperature of my hard drives might go up a bit. Anyway,
thanks for the help, folks.<!-- ~MESSAGE_AFTER~ -->
