Think bigger, I want a SoC "Server-on-a-chip" design. Integrate everything into the silicon for processing, network and basic storage I/O. I want to drop a big block on a simple 4 layer PCB and route memory, ethernet physical pins, USB, storage interface, and a power bus and that's it. The only other parts on the board are some passives. Then I want to duplicate that 64x or so on a rack sized PCB, put some cooling on the chips and board and have a super dense, super powerful cluster of ARM processors. Racks and racks and racks of these for as far as the eye can see...
