This is my first post - hope it fits your interest criteria...

I plan to assemble a computer specifically for sound recording and am
considering putting in a Yesico FL-420ATX Power unit, which has no fan and
vents the heat outside the case.

This has obvious advantages, enabling me to record directly to the HD
without fan-drone.

I just wanted to know if anyone had tried this and whether there were any
drawbacks, before I go ahead.

It seems like it would be a good start, but understand that the power
supply fan isn't the only source of noise in a computer. I've found
CPU fans to be more objectionable, and once you get those down to a
tolerable level you start to hear the disk drives.

There are a number of "quiet" CPU fans but the published
specifications haven't been impressive enough to me to spring for one
to try. It's not that the published numbers don't look good, it's that
I don't know how much of an improvement they'll be over what I have
now. It's difficult to quantify the acoustic performance of a fan both
because they're all really pretty quiet (hard to measure without a
very well controlled environment) and also because the spectrum of the
noise at a given amplitude makes a big difference in how bothersome
the noise is. Reducing the fan speed lowers the frequency of the noise
and almost always makes a noticable improvement in the annoyance
factor.

The best approach is to simply get the computer far enough away from
your microphones and your ears so that its noise won't be a problem.
An alternate approach is to buy or build a sound-reducing enclosure,
but you still have to provide ventiliation.

The Yesico looks like it might be intersting, but a quick look at the
first page Google came up with doesn't indicated that it's easily
avaialble in the US, so it's not on my radar at the moment.
