I don't thing you can label one brand as better then another because they are all designed the same. I have An Acer AS 8950G that I was able to access to drive bays and 4 memory slots and the wireless to add my own components. Now I have an Alienware where I have access to the optical drive, a MSATA SSD slot and 2 drives. I only have access to 2 of the 4 memory slots. You have to take off the keyboard to get to the other 2 memory slots. That was also the case when Acers next model similar to my 8950 and the 8951 had 2 memory slots on bottom and 2 on the top.
