How much to sell Toshiba Satellite Laptop?

Have been thinking about selling my Toshiba Satellite Laptop. 2gb ram, processor: Intel(R) Pentium (R) Dual CPU T3400 @ 2.16GHz 2.17 GHz, and 32-bit operating system. I have 2 different harddrives but i dont know which would be better to put in when i sell it. I have a 500gb harddrive with non-genuine windows 7 and i have a 250gb harddrive with genuine windows vista. Minor stratches on the top. My computer works fine but the only problems are my computer says there is something wrong with my battery(although it works fine) and my graphics card isnt good so it wouldnt be for a gamer. Thanks for any help!!
