i do not know how the reputation of Dell is in your country.
Here it is known as a big firm that sells used parts in so called new pc's. Even cases are known where people found programs of previous users on their pc. If you get a good system it rocks but service and helpdesk there a mess.

Why don't you built your own pc. You could have a system like that for half the price. However i am not sure if hardware is expensive in your country.

BTW i am from the netherlands and i just read your aiming for alternate much better choice
