Installing Mac OS X Leopard: the Hardware Build

1. Install the motherboard and CPU: You can follow these instructions almost without variation, but the heatsink and fan installation, in particular, is a touch different. Rather than hooking the heatsink to your motherboard, the included Intel heatsink pops into place. For a more detailed description of how this works, consult your motherboard's manual and the manual included with your processor.
2. Install your RAM: The only thing you need to keep in mind when you're installing the RAM is that you should install the matched pairs—that is, the pairs that come in the same package—in like colored slots. This isn't strictly necessary, but it's a good practice and generally means better performance.
3. Install the video card: These instructions actually detail how to install a PCI card, which is just a more general way of looking at your video card. The card we're using is a PCI Express card and should be installed in the top (orange) PCI slot.
4. Install the hard drive and DVD drive: Your hard drive is an SATA drive, which is not the type of drive installed in the instructions (though they do address SATA drives). Just connect one of the power supply's SATA power cables to the drive and then connect the drive to the red SATA connector on your motherboard (it's labeled on the board as SATA1). Follow the same basic instructions to install your DVD drive but plug the drive into one of the other SATA ports (I used the SATA4 port).
