Yes, they do. The preamp is built-in to any soundcard with a "mic"
input. A sound card mic input will be high impedance (a.k.a. Hi-Z)
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).
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).
