Pity. All that fan noise should make a good random source.
In all seriousness though, you can cut costs so far that you can
no longer implement a security architecture that depends on
cryptographic random numbers. If you need that kind of
architecture, then pay for a random source. Retrofitting a USB
dongle might be the cheapest solution for existing hardware. A
random source should be a required feature for new hardware
which will run applications requiring cryptographic random numbers.
