Looking for specs on particular CF31 model

Looking at a used CF31 that's for sale. It has no OS but apparently has a 160 GB HDD, 4 GB of RAM, and an i5-520M (2.4 GHz) processor. Model code supplied by the seller is:

CF-31AWA70PA

Is anyone able to cross-reference this and tell me firstly what the base system spec is going on that code, and secondly where it sits in the CF31 range and if it's a spec that's good to have.

Thanks, Craig.
