Geek, but also I'm a professional editor that uses Final Cut Pro and various other tools for OSX.
Back when I first got into Hacks, I hated the idea of ponying up for Apple's Mac Pro. Even years ago, I thought it was too much money for essentially outdated hardware. Same hold true today; as of this writing the updated MacPro still isn't actually in anyone's hands.
I wasn't up for hopping on that "wait for years with outdated equipment" bandwagon. (And there's no other desktop Mac other than the Pro that I'd ever have been happy with.)
So in the 5 years I've been building Hacks, I'd estimate I've spent maybe the same as a fully loaded MacPro would have cost me back then- but I've had multiple system upgrades, at least three full overhauls of my system (motherboard, RAM, CPU, graphics card) tons of hard drives, etc. Soon I'm planning an upgrade to Haswell.
For me, Hackintoshing has been a perfect fit. I much prefer to build and upgrade my own desktop computers, than to be stuck with Apple's glacially slow upgrade cycle. From day one, I've gotten my work done with my Hacks more comfortably than I would have on anything but the best MacPro.
Some people like to believe Hacks aren't stable and therefore can't be relied on for doing work, but those people are doing something wrong. My experience from day 1 has been exactly the opposite- my Hacks have been rock stable and easily are the most reliable computers I've ever owned. I've actually seen more kernel panics on my 15" retina MacBook Pro than I have on my signature Hackintosh. (For some reason, the rMBP has some issues with its USB ports and will on occasion KP after waking from sleep. Ironic, because my HP Probook 4530s Hackintosh laptop used to have similar issues when I first set it up, but those were since ironed out by the ProBook community here.)
Anyway, what's drawn me to it is extreme bang-for-buck, plus I love that I can build exactly the system I need for my work, without spending anything close to Apple's prices.
