To avoid condensation i vill use two tempdevices, either thermistors or Pt-100, in a wheatstonebridge. One on the coldplate and the other outside the case to measure roomtemp.
This setup will keep the coldplate at room temp all the time and will not require a separate PSU.

It sounds like you and I should get together... I'd still isolate for condensation though, just in case. Are you planning on cooling the Pelt with air or water? I would still use a seperate PSU, just to make sure that there's no extra load that will make the PSU's voltage drop to where the mobo/cpu crashes, but hey, that's just me.
