Not all memory will be compatible with a certain model prebiuld. You'll note the "guranteed compatible" statement there since most older prebuilds use value ram not any gaming/performance memory. On some older models you will find that you had to use single sided not dual sided memory seeing ic chips on one side only.
what's simple to you and me could be very confusing to a novice, people look at me like 'm crazy when I try to explain how easy it is to build a computer...
I've never run into any problems with memory, maybe I'm just lucky, also, I have a few friends who have the exact same model Dell and every stick of RAM I've installed to upgrade their system has worked, I just think those "guarantees" are a way to squeeze more $$ out of people who just don't know any better...
