Howdy!
I'm from South Africa, in a city called Durban - the home of sunshine, surfing and babes!
I've been using a HackMac as a film production machine (Adobe Suite) for a little over two years - started with Snow Leopard via tonycrap, migrated to Lion when I got a new PC, and am ready to take the plunge into Mountain Lion, for its added GFX card capabilities.
Being in film production, a Hackintosh was a no-brainer - the only alternative to a $4000 Mac Pro, in an industry almost completely dominated by Apple hardware. Needless to say, although I love Apple build-quality (typing this on a Macbook Pro, Retina!) the pricing in South Africa is just ludicrous, and I think we all know that you can get a lot more bang-for-your-buck if you build your own PC.
I found Lion to be incredibly tricky to install, considering my GTX 570... Getting full graphics to work was stretching the limits of my already limited OSX knowledge, but eventually (using a combination of forums, guides, Youtube and luck!) I built a perfectly working Lion box, complete with Nvidia CUDA, Firewire 800, a home-built WIFI card (using a Airport mini-PCI bought on ebay!). The box has been running solidly for a year or so, even updating to new Lion versions every now and again.
I've been using Macs and PCs for... what feels like forever, and although I wouldn't consider myself an expert in any one particular field (no heavy programming experience), reckon I'm a jack-of-all-trades, and can figure things out pretty quickly - not afraid to use Google!
Keen to get Mountain Lion up and running, heard good things about it and my GTX 570. My specs:
Mobo: Z68X-UD4-B3
CPU: i7 2600K
RAM: 16gb Patriot Sector 5, DDR3
GFX: Gainward GTX 570 Phantom
Optical: Sony Optiarc
PSU: Cooler Master Silent Pro 800w
