Keep in mind that you need to put this in a server with DIMMs, power supplies, and disks. It will likely come out to $20-30k all in for one server depending on how much margin your system integrator wants. You probably want two in case the first one fails, and you may want as many as 3-4 for true 24/7 availability, plus a backup service.

The math still doesn't look too good for the cloud, though.
