Is there a provision on this online laptop buying service from official dell website that I can select my own system requirements while buying a DELL laptop? I want to buy a Dell Inspiron 15R 5537 type laptop without windows 8 because I have windows 8 already in my other laptop(my brother's) i.e. I want ms-dos version of it with 8GB RAM and 1 GB graphic card or something more customization(touch enabled)............. Please reply as soon as possible.........I have to buy this laptop in this upcoming week ............ I know that alienware offers this type of customization service. But does DELL offers this too?
