Golden Build?
Which golden build did you use? Tonymacx86?
They've come a long way since the netbook.
I can only go off of my own experience. I was really just giving it a shot since I've always just built my own PCs for 25 years. I already had a mac mini so I didn't have much to lose if it didn't work.
So what I did was put together one of the 'golden builds' which essentially is using components that are already in use in current Macs. No reaching at all, just as vanilla as you can go. What I ended up with was something similar to the maxed out iMac but with a 2gb Geforce 650ti, so a little better in the video department. Costs out the door I think were somewhere around $900.
The goal was: no trouble. No fiddling with it. No kernel panics. No weird problems or incompatibility issues, etc. It had to be rock solid.
It took me about 6 hours total to build the machine, install everything and then get OSx to work. Admittedly, it did take about 2 hours of troubleshooting to get all the components working (sound, wifi, bluetooth, etc). But since I've set it up, I've yet to have any weird problems. I've got it set up with Time Machine and I buy apps frequently on the App Store and pretty much do anything I normally do. I even upgraded it to Mavericks without any hiccups. Like I said, if this thing has any weird issues it's pretty much a straight shot to a 2012 Mac Mini but so far so good!
