Running Apple’s Mac OS X software on PC hardware has been a hobby for some enthusiasts for a while. There are several forums on the Internet that discuss the topic extensively, but here is a brief article with one of the possible hardware configurations that can run OS X Lion or Mountain Lion.

Intel i7-2600k running at 4.2Ghz Amazon $289.99
(Frequency multiplier set to 42 in the BIOS)
Cooler Master Hyper 212 EVO CPU Cooler Amazon $29.56
Corsair Vengeance Low Profile 8 GB (2x4GB) Amazon $54.03 (low profile version lets you add another 8gb (2x4gb sticks) later without hitting the CM Hyper 212EVO cooler’s fins)

If you need more GPU horsepower, these are the best price/performance deals:
SAPPHIRE AMD Radeon HD 6870 1GB GDDR5 PCIE Graphics Card Amazon $169.99
Native Apple WiFi with AirDrop support $35.69
Atheros AR5BXB112 AR9380 Dual-Band Mini PCI-E 450M Wifi Wireless Card 802.11n Amazon $34.05 (the same board as in mid-2011 Mac Mini)
Mini PCIe to PCIe Express Adapter + 3 WiFi Antenna Amazon $1.64
Native Apple Bluetooth with sleep support $14.38 (+soldering skills)
Apple A1114 Bluetooth Card Board Module 820-1829-A PowerBook MacBook Pro w/Cable eBay $9.99 (read this great post with instructions how to adapt the module)
11″ Extension cable for a standard USB motherboard connector Amazon $3.99 (to be cut and connected to the above module)
2 x 1N4007 diodes Amazon $0.40
DSDT: DSDT Database
SSDT: Select i5/i7 overclocked SSDT option in the MultiBeast installer.
Smbios: After long tests and benchmarks I’m sticking with MacMini5,3 (mid-2011 MacMini Server), it has better SpeedStep settings compared to MacPro3,1 and MacPro5,1.
Ethernet: Realtek official driver has better stability and speeds compared to lnx2mac ethernet drivers under heavy torrent load for me. Both are available in the MultiBeast installer.
WiFi / Bluetooth: Don’t repeat my mistake and don’t tap power for bluetooth from the miniPCIe adapter’s 3.3 volt line, it’ll result in immediate wake upon putting computer to sleep. You have been warned. Use the 2 diodes hack or a proper 5v-3.3v regulator to bring the USB voltages down. The A1114 / 820-1829-A apple bluetooth adapter uses 3.3 volts, not 5.
Native WiFi with AirPort supported and native Bluetooth with full sleep and wake with Apple Magic Mouse.
