Yes you are right about Dell. Most of their hardware all being propiatary. I am still rocking my Dell XPS 730x I purchased back in 2008. If it would not be for my trusty "dremel" I would have been out of business long ago. But my 730x case is like my girlfriend. When for the first time I laid my eyes on the 730x case I instinctively knew it would be high maintenance and expensive. The first question many enthusiasts ask me: "Where did you find this case?" Yes Lola when I first met her she turned my imagination rock hard and I instinctively knew that I was going to be in for ride. So in this regard Dell wasn't all that bad afterall.
