This is a most excellent place for technology news and articles.
Same thing with HP. Their "Pavillion" series of Towers contains a proprietary motherboard and power supply. Also, on the model a friend of mine had, the CPU was AMD, but the cooler scewed on top was designed for intel-purposed boards, so it looked kinda frankensteined.
So in essence, it's the same with HP.
