1) The hardware stuff is common knowledge - as long as your a half intelligent consumer who has done some initial research before making their purchase. You're not buying a 2350 if you're a hardcore gamer. I think Dell makes it relatively clear that Integrated video is your only choice as far as that system goes.
As far as power supplies - you're not getting a huge, highly powerful power supply when you order a Dell. It's a fact of life, get used to it.

I have no problem with that - due to the fact that any Dell systems I've owned have always had 100% trouble free power supplies - EVEN the lower end ones.
2) Dell knows what they're doing. If they didn't, they wouldn't make their billions, and they definately wouldn't be a top PC maker. If they had true issues with their power supplies - they'd change their ways. But I don't really see a lot of people complaining about faulty power supplies. On top of that, Dell isn't targeting the user who is going to be throwing in or changing components every month. If you want to do that - build your own system. No one is saying that you're not allowed to do so.... Are they?
3) Your opinions on support and shady business practices are subjective. Most people have no problem with Dell, and most (including me) have minimal issues with their support department. Trying to put forth that "most" or "many" experience problems with their support due to a few crazy stories isn't very convincing... In my eyes, at least.
