The only advantage these hyperscale purpose built computing platforms provide is elimination of the profit taken by HP, IBM, Dell, etc. They are complaining about the PC heritage in the server world- this is actually a huge convenience in that it is standardized hardware (so for example, it's easy to install any software made for PCs on them, including Linux). The cost of this compatibility is not very much these days (in terms of silicon area). Blade servers had centralized power supplies since forever ago.. Also you can certainly get servers without CD drives :-) Rack front and back panel area is actually a limited commodity, so for example many modern servers are just packed with 2.5 inch drives..
