What I was thinking of is boxes that are accidentally Hackintoshable. It doesn't say anything on the website, box, in instruction manual. Just a few hundred people register on various Mac forums to report "wow, I managed to Hackintosh this Asus VerySmallBox PC veeery easily". And one or two of them publishes an easy installer, -Beast style. I don't think Apple can sue anyone for accidentally using components that can be hacked.
Fair enough, I now get what you say. From my own experience, almost any gigabyte board is already compatible. Someone using components from tonymacx86, will give you a 100% success rate.
I managed to build a few without even installing custom drivers or any hack.
Soundcard:
- I never had issue with built-in card but had to install drivers for it
- My secondary internal HT Omega card never worked.
- External USB sound card (or USB DAC ie Dragonfly, Emotiva,...) won't require any specific drivers, so if you have problems with the internal SC, this is a good solution
- external web cam (will give you a mic+camera) for facetime
Board:
- gigabyte : works without any hacks
- asus: had to patch my bios but didn't require anything specific after
Video:
- GTX 680 works! can also install Nvidia's drivers. Late 1070 or 1080 may not be supported at this moment
- integrated GPU for i5: worked out of the box, no drivers
Ram :
DDR3 2166mhz : no issue
Wireless: not tested
Bluetooth: working via 10$ dongle adapter
Network card:
- Built in NIC worked
last time I checked my system was beating the biggest fully loaded iMac..
