Hardware Recommendations was created for questions seeking a *specific* hardware recommendation given a set of definitive requirements. The OS X question was off topic, but the multiple monitor question was salvageable.

The https://hardwarerecs.stackexchange.com/questions/270/what-are-the-pc-hardware-requirements-for-os-x-to-run-on question is asking what system requirements are needed for a hackintosh. There doesn't seem to be a hardware recommendation question hidden in there.
The Graphics card that can support three monitors question, though poorly worded, is actually asking for a graphics card recommendation to meet their requirements of three monitors and their usage pattern.
