I am looking at getting a used dell x200 really cheap and then upgrading the whole system. you can usually find a very slightly used one for around $400 since they are on average 2 years old. My only question is do they make a pentium M processor for this model. I know they made one for the later x300 that followed the x200 in production. Would the x300 motherboard/processor fit in the x200 since the computers are the same size???? the x200 comes with a pentium 3 933MHZ processor. Please help me.
