My experience running a hack for 6 years:

Pro:

- best desktop OS there is reg security and privacy

- my hardware, BD-RE and 4TB drives, full size GeForce

- 1/4th the price

Cons:

- learning curve is a bitch, but done once

- updates can be tricky, thanks to Nvidia :)

- for IT pros / hackers only

Result is indistinguishable from real iMac, sleep and all works.

Once you'd settle your clover.config, it is mostly painless. I even have FileVault on my volumes :))
