I take a vaccum and put it up against the vents on the p/s. The fan
starts spinning and it sucks the dust out. Its easy and seems to work
for me. Could this cause any problems with static electricity?

From what I gather, air/wind produced static electricity is caused
by dust particles. So the answer would be Yes, but who knows
whether it in fact would. Compressed air is probably better since
it is clean. Some people might argue that static electricity
really is not a problem, but parts do fail and (since you cannot
troubleshoot them) who knows why they fail. Eliminating leads
(like static electricity damage) at least might allow you to guess
about why something failed.

Good luck and have fun.

I do see what you mean. I have a "horizontal" desktop pc at home (as opposed
to the normal vertical tower), and the only dust problem I have is around
the cpu fan. When I do vacumm it out I always include the power supply, and
have not had any noticable issues.

If you are considering getting one of these pcs (or if you already have one)
then I'd recommend making a note to open it up after two or three months to
see how much dust is in there. Then you can make a call as to whether its
worth vacuuming out regularaly or not.

I'd worry more about the fans spinning too fast. I'd block them from
moving by using something nonconductive and tough but not brittle,
like a plastic straw. Don't use anything metal because there's
exposed high voltage right behind the fan, even when the PSU is turned
off by its rear switch.

One former American TV manufacturer issued a service bulletin warned
technicians about static electricity from vacuum cleaner wind causing
damage to chips, but I seriously doubt that's a real problem with a
power supply because their chips aren't as delicate.
