Its not that old alchav21
But Versa_E3100, its pretty old and comes with very little ram (128MB?). I don't think you will be able to successfully burn a DVD with it. Also the internal HDD will be very slow. The optical drive in your laptop is IDE and is not popular anymore. You can get them on Ebay, search for "IDE laptop dvd drive", then on the left side of the webpage select the option to view only 'new' condition items.
But if your buying this to burn a DVD, then I would suggest to save that money for a new laptop.
