I work in a lab where we analyse smelly components from polymers. We use a TGA (thermo-gravimetric analyser) which is a balance in an oven and monitors the weightloss at a certain temperature, and a GCMS (gas chromatograph/mass spectrometer) to identify the volatile components. In our experience the components causing the smell of a polymer are only a very small part of all the volatiles from the polymer (mostly less than 1% of all the volatile components). And, when heated to 80C not only PVC's lose volatiles, but also polyethylene, polypropylene and a lot of other plastics (the volatiles are not only the plasticizers, but at these temperatures the polymers start to lose low molecular parts). We also analyse materials with resins (which come from wood), these resins give off much more volatiles than similar amounts of plastics! So a computer out of wood will probably be not a good solution for less volatiles...
