The major advantages you have with DIY are:
That's non-sense. Certain components, they might do that, but usually they buy in enough quantity to be able to get inexpensive customized parts (i.e. power supplies with power distribution across the buses fitting their computers, not a generic one). Dimension/Inspiron lines are built for lowest cost possible and made for home environment, but their Optiplex, Precision, Latitude lines use same parts through the model and are actually network certified, meaning they've been thoroughly tested for network environment with thousands of computers.
Review sites don't have the extensive testing facities available to Dell, Compaq etc and they don't test for network certification.1. You can choose the brand/function of the mobo and other parts based on reviews
This makes what difference?2. If a part is defective, it is usually replaced with a new part (Dell replaces with refurbished parts).
3. You have a wider selection of choices (e.g. AMD)
4. You don't have to deal with the advertising and 3rd party garbage that Dell puts on your system.
Wider choice doesn't equate superior reliability which is the topic of this therad and you're only speaking of the consumer line Dimension or Inspiron.
Business class Dells are more reliable than a gamer's wet dream rig as you can see from relatively low failure rate of institutions using thousands of those at the same time.
