As I mentioned before, if the devkit motherboards were available at a 
reasonable price (Compulab make some Armada 510 boards for an almost 
acceptable $350 (I personally find an extra $100 on top of a D2Plug 
price tag to be worth it for ATX form factor, extra PCI/PCIe slots and 
an extra gigabit ethernst port), but you first have to have a $900 dev 
kit (which includes a mobo and a year's worth of support). Having a 
higher speed dual core processor would be great.

Won't the GPU suck up an unreasonable amount of power? What are you 
planning to use?
