Just built a new basic rig for Hackintosh:

• GIGABYTE GA-H55M-S2V
• Intel Core i3-550
• XFX nVidia GT240 1GB DDR5 Graphics Card
• G.SKILL 4GB DDR3 Dual Channel Memory
• Samsung Spinpoint F4 HD322GJ/U 320GB Hard Drive

Runs very smooth. Only hiccup is the wireless network for it; I have to reset the USB adapter (Linksys WUSB600N v2) when I wake the computer from sleep or a fresh boot. Otherwise, sound works, remapped keyboard (since it puts command on the Windows key, I mapped it to the CTRL key) and all is well .
