Read this to get a general idea:

Some more about actual physics behind this:

Easy way to grasp the pure basics form this image:

The most important part of the system is obvioulsy a peliter module.
In Europe it can cost form 10 Euro for a 70-90W up to 120 Euro for 150-200W (cooling power). The price will vary, if you buy in bulk its cheaper.
You will also need heat exchangers (i.e. heat sinks with fans) to transfert heat to and from the peliter module.
Basically a computer CPU/GPU heat sinks with a fan attached to it will do. Dont forget about power supply, peltier modules are DC.

There is loads and loads of info on the internet. Just use google ;)
