Since ASIC's are specific and not upgradable as RISC, software-wise. Why has no one try to make something built on them?

Thinking of getting a 10 GH/s or larger ASIC miner. Was thinking of the Monarch by Butterfly Labs, but heard they are sketchy. So, I would KNC and the other companies instead. Thanks in advance for the help.

Is there anyone that make one and is optimized for cooling? If not, I'll just build a custom one from old PC cases.
