Hi. I'm putting together a Hackintosh for my brother's Christmas present (shhhhh ). I've been going over parts like crazy and have narrowed it down to the following list: Gigabyte GA-B75M-D3V Intel Celeron G540 (Own) G.SKILL Ripjaws X Series 8GB Seagate Momentus XT 500GB XFX Radeon HD 5450 Edimax EW-7722In (Own) XION XON-710P Logitech K400 My goal is to build a machine that will run Mountain Lion (ML) as smooth as possible. This machine will be used to surf the web, play games via emulators, stream Netflix, connect to iPhone, nothing intensive in the least. My questions mostly concern the compatibility of my selected parts with ML. I'll list them for expedience: 1. Is it safe to assume that if a video card works with one build that it will be compatible with other builds? 2. Since HD 2000 graphics aren't supported, do you connect the display via onboard outputs or the outputs on the video card? 3. Are the onboard Network and Audio of the MOBO supported by ML? 3. Do you foresee any other compatibility issues with ML? This is going to be my first Hackintosh and I'm sure I'll have more questions as I continue my research. I'll post them as I think of them. As always, thanks for your help and happy Hackin!
