Yes, they do. The preamp is built-in to any soundcard with a "mic"

and have an amplifier (called a preamp in this case) on it in order to
bring the signal up to line level (before it hits the ADC). On Thu, 2007-11-01 at 08:27 -0700, william

I think what
you need is to use cheap computer mics, not music-quality
ones, that should only need to plug in to an 1/8th-inch audio in
connection on a sound card. I don't think those kinds of mics require a
preamp of any kind.
But I agree that is what the OP wants, assuming the
computers in
question will have mic inputs (I think most motherboards have them
integrated these days).
The assorted desktop PCs around here all have mic inputs. So does my
Toshiba laptop. With the popularity of Internet telephony like Skype and
Vonage, I suspect it's probably almost mandatory in laptops now.
