Not necessarily true, self built systems can last a lot longer than prebuilt. It depends on who builds it, if they can be stuffed doing a good job, did they have a big night earlier, etc, etc,etc. If you do it yourself, all the above apply, but you can leave it and come back to it. For general windows work, not 3d gaming etc, Alienware is extreme overkill, not to mention expensive. You could have a look at Dell if you are desparate, (again expensive), but nothing beats homebuilt if you can do it. Also with self built, you get to choose what goes in, what quality you use,and also what brands to use. Not helpful Im sure, but my 2cents. PS which state are you in.
