Ive been saving up for a laptop, and i just realized that the laptop I've been looking for doesnt have an internal DVD slot. On the picture's theres an example of an external DVD slot, but im not very gifred with technologics, and i dont know if it says that i WILL recieve that DVD slot, or that i have to pay more for it. If i have to pay for it, i cant find where it is in the customizing 'add on's'.

this is the laptop, except its an upgraded model costing 0
